In 1988, Electroswitch acquired the Type W Switches and Relays from Westinghouse Corporation for the purpose of maintaining a high level of support and assistance to exist-ing customers in the utility industry. Since that time, many changes have been made in switch technology and these models have been replaced. However, Electroswitch continues to offer the Type W Switches for customers needing replacements into existing systems that would require panel rework.
NameplatesType W Switches are supplied with a standard black nameplate that can be engraved to your requirements. Circuit Breaker Control Switches have a cutout in the nameplate for a red and green target indicator to show the last manual operation of the switch. Special engravings should be indicated clearly at the time of order.

They are long operating life, low maintenance switching devices, specifically designed for the severe conditions of industrial use. They feature low operating torque; high pressure line contact; flame retardant, non-tracking insulation; and precision made non-ferrous parts. All current carrying parts of 200 ampere switches and larger are heavy silver plated. Switches up to the 1000 ampere size feature glass fibre reinforced molded bases for high strength, precision contact alignment, and light weight.
DUAL CURRENT RATINGTypes S1, T2 & T3 Heavy-Duty Rotary Tap Switches are dual rated for both continuous and inter-mittent duty: Continuous/intermittent. Continuous Current Rating is based upon a 40˚C temperature rise and a 40˚C ambient. Intermittent Current Rating is based upon a 40˚C temperature rise, a 40˚C ambient, a 50 percent duty cycle, and a one-minute integrating time.
SINGLE, TWO OR THREE PHASE
2000, 3000 and 5000 ampere Heavy-Duty Rotary Tap Switches are custom designed and man-ufactured for each specific application. They provide the same fine materials, workmanship and quality as the lower ampere switches and feature custom design, low operating torque, high pres-sure line contact, fabricated insulated bases, precision made non-ferrous silver plated parts. Along with the 800, 1200 and 1600 ampere switches, they have built-in rotor lubrication systems.
All switches are supplied with escutcheon and handles. The handles have a provision for two padlocks as a standard feature.

ELECTROSWITCH CONSTRUCTION DETAILS DETENT-ACTION SWITCHES
Electroswitch Detent SwitchesElectroswitch Detent Switches are a heavy-duty design that is very versatile and enables standard units to satisfy a great variety of complex switching applications. They are modular in that several subassemblies are stacked together to form a rigid rugged device. Figure 1 shows a cut-away view exposing the basic components.
OverviewThe mounting plate (1) connects a detent assembly (2) to one or more contact decks (3) and finally a position limiting stop plate (4). These assemblies are bolted together along with a steel shaft (5) and a handle (6).
The Electrical DesignThe Detent Switch contacts operate on the time proven reliable principle of knife switches – double-sided, double-wiping, spring-wiper blades closing on both sides of a terminal. This design is shock-proof and virtually bounce-proof. Figure 2 shows a typical contacting arrangement.
The Detent AssemblyThe detent assembly contains a specially designed star wheel and up to four spring-loaded ball bearings providing snappy positive indexing. Spring return switches use a coil spring in place of the star wheel/spring/ball bearing arrangement.
The Pull-to-Lock MechanismControl switches generally have positions both 45˚ left and right of the normal vertical position. The handle spring-returns to the normal position. The pull-to-lock mechanism enables an operator to turn the handle beyond the left (normally TRIP) position to the 90˚ location, pull out the handle and thereby lock the switch into this position. This precludes the possibility of someone inadver-tently closing a circuit-breaker when it is desired that it stay in the tripped position.
The Contact Deck AssemblyThe electrical parts are contained within sturdy phenolic moldings that provide individual insulated compartments where all switching takes place.
An insulating barrier completes the contact deck assembly. The barrier not only separates one contact assembly from another but also provides a tight insulating compartment. With this construction there is no need to add a dust cover.
Positive, reliable, maintenance-free operation results from the double-sided, double-wiping, self-cleaning knife-blade moveable contacts.
The barrier next to the stationary terminals is clearly marked with numerals for Series 24 and 31 that correspond with the wiring diagrams.
Terminal screws secure the external wiring to the terminals.
Jumpering may be done right on the switch providing a simple and neat arrangement. Silver plated brass strap jumpers are available for adjacent contacts – either between adjacent contacts on the same deck or the same terminal location on adjacent decks. Wire and lug jumpers are also available. Jumpers are already supplied assembled on the typical instrument switches, illus-trated in this catalog, simplifying field wiring. All you need to do is connect the instrument leads and the line wires.
The Stop PlateThe steel stop plate assembly includes a steel stop arm that is connected to the shaft and a steel stop plate that contains tapped holes. Stop screws are inserted in the field to limit the positions to the number and location desired. This externally adjustable position limiting feature allows the use of standard switches for many customized applications. The limit screws are supplied assembled for typical instrument switches.

ELECTROSWITCH
Snap-Action SwitchesSnap-Action Switches use a design that enables them to combine a small number of basic parts to satisfy a wide variety of requirements for selector and control switching of power circuits. Standard switches built with this design for 15-, 40-, 60 -, and 200- ampere capacities are listed in this catalog. However, the cataloged units merely indicate switching possibilities; we will gladly recommend other combinations, based on our experience, for specific requirements.
The Electrical SystemThe electrical system comprises two or more stationary contacts (9) and one or more sets of movable contacts. These are pairs of spring-metal blades (8) that make high-pressure, low-resistance contact on both faces of the stationary contacts while bridging two or more of these contacts. The stationary contacts fit in radial grooves (12) in the rim of molded insulating disks (7), within which the movable contacts are carried on an insulated shaft (11). All “making” and “breaking” of electric circuits takes place within the closed spaces between adjacent disks. Their quick-break action makes these switches particularly suitable for direct-current service. The ends of the stationary contacts extend outside the insulating disks and serve as connecting terminals (10 ). This one-piece contact/terminal construction minimizes series resistance and heating. Depending on current rating and on-wiring requirements, the terminals may have tapped holes for connecting screws or clearance holes for bolt connection of cable-lugs.
The Mechanical SystemThe mechanical system is designed to provide uniform high-speed “make” and “break”, regardless of whether the operating handle (1) is turned rapidly or slowly. Turning the handle through approximately 120˚ in either direction winds a powerful coil spring (3). When this is fully wound, the indexing plate (4) is momentarily withdrawn from the locking plate (5) by an eccentric cam. The drive-shaft and movable contacts then snap rapidly to the next position. The indexing plate holds them until the spring-drive mechanism is again operated. Transit time is about ten milliseconds.
AssemblyThe snap-drive mechanism, mechanism-cover (2), locking plate, mounting bracket (6), insu-lating disks, and back plate (14) are stacked on side securing rods (13) and bolted firmly together to form a rigid assembly. The handle is keyed to the operating shaft and secured by a screw.
Stationary ContactsNon-shorting (break-before-make) contacts are standard in all the ratings and circuits shown in this catalog.
Shorting (make-before-break) contacts, required in some special circuits, are available on order.
The “sweep” contact maintains the connection with the rotor through consecutive positions.
Moveable Contacts (Rotors)The simple, straight-across rotor bridges stationary contacts in the same insulating disk. It provides single-throw switching in Circuit 1 and double-throw switching in Circuit 6.
The right-angle-blade rotor provides a double-throw switching, with an intermediate OFF position, in Circuit 7.
A multi-fingered blade is combined with a single-contact blade to form a composite (double-deck) rotor that interconnects stationary contacts in adjacent disks. Suitable blade arrangements provide double-throw, triple-throw, or four-throw switching.
Insulating Disks (and Circuits)The insulating disks, molded of phenolic per MIL-M-14, have three functions. They hold the stationary contacts, they form enclosures that contain all making and breaking contacts, and they provide both mechanical and electrical separation of switching sections.

ELECTROSWITCH
Cam-Action SwitchesThe design principle allows the combination of a relatively small number of basic parts to satis-fy a wide variety of requirements for selector and control switching in power circuits.
The Mechanical DesignThe switch features a modular design with switching decks (3) stacked with a detent mecha-nism deck (6), a mounting plate (12), and a handle (13). A steel shaft (10) couples the han-dle to the operating parts. Two steel securing rods (11) are used to bolt the whole mechanism rigidly together. The basic parts and assemblies are shown below.
The Detent AssemblyThe detent assembly (6) consists of a spring-loaded detent block (7) with a roller coming into contact with a notched detent wheel (8). This detent wheel provides the standard 45˚ detenting as well as optional 30 ,̊ 60˚ or 90˚detenting. The stop arms (9) are located under the mounting plate. These limit the angular rotation to the desired number and location of positions.
The Contact AssemblyThe contact assembly (3) consists of a rigid thermosetting plastic housing, two sets of stationary contacts (5), and two spring-loaded (16) movable contacts (1) held in cam followers (2). Floating on the shaft and held within the contacting chamber are two independent cams (4). The cams are notched to provide the contact “close” angles desired. The contacts are spring-loaded closed and mechanically opened by the cam action to avoid sticking. The terminal screw (15) and pressure clamp (14) will easily accommodate stranded wire with lugs or solid wire, either with or without lugs, compatible with switch size.
Contact OperationThe contacting consists simply of shunting two isolated contacts to make a circuit. Two independent sets of contacts are placed in each deck. The moving portion is spring-loaded to close the contact. A notch on the cam is affixed to the operating shaft allowing the moving contact to spring close, bridging the stationary contacts.
The movable contact (1) is spring-loaded (16) and held by the cam follower (2). It makes a circuit with the two stationary contacts (5) when the cam follower enters the notch in the cam (4).
Identically, the same thing is happening with the contact set on the right. This circuit is held open by the cam and will close when the notch on the second independent cam is rotated around and comes in proximity to its cam follower (the second cam notch is illustrated by the dotted lines – the cam is underneath the other one).
We show the contacts pictorially to agree with typical detailed schematics and wiring plans. This simple system makes the switch contact arrangement, performance and location independent of the switching action required. The switching action is varied and controlled by the shape of the cams – allowing a virtually infinite number of combinations using a few standard parts. This simplicity and flexibility makes it easy for you to design your own switch – using familiar con-tact language. You eliminate the worry, long deliveries, high costs, etc. normally associated with special switches.
Note: The terminal numbering consists of individual numbers for each terminal for positive identification.

ELECTROSWITCH
All About TestingSwitches are tested in many ways to prove their capabilities and reliability. Electroswitch uses a combination of test methods to provide meaningful data for all applications. These include:
1. Cycle it mechanically until it breaks. This is usually an academic test since switches that do not switch electric power are not needed. An exception is a setup switch whereby the switch sets up a complicated circuit and then a circuit breaker switches the power. All testing is done under electrical load.
2. Test under an application oriented specification – something that simulates actual operat-ing conditions such as environment, overloads, surges, etc. UL1054 on SPECIAL USE SWITCHES and CSA C22.2 on INDUSTRIAL CONTROL EQUIPMENT for use in Ordinary (non-hazardous) Locations are probably the best specifications in widespread use. The Series 21, 24, 25, 28 and 31 are UL recognized and CSA certified to these specifications.
3. Test at different ratings until destruction to determine ultimate life (destruction could be mechanical failure, shorting out, dielectric failure, excessive heat rise, etc.). The test condi-tions are outlined on the SELECTOR CHART for each type of switch. The results are summa-rized below:
Both UL and CSA testing consists of two parts:
1. Product testing to the specifications.
2. Follow-up service by UL and CSA personnel at the factory, including inspection and test-ing to insure that the quality and reliability is maintained.
If all conditions are met, the switches are considered “certified electrical equipment” by CSA and “recognized components” by UL and the applications are subject to review by these agencies to assure suitability.

UL and CSA Ratings
These recognized or certified ratings are not necessarily the limits of switch capacity. They represent the acceptable tested ratings to comply with individual standards.
Tests include:
1. Overload – 50 cycles of operation. UL – 0-10A at 150% rating ... over 10A at 125% rating CSA – 150% rating
2. Endurance – 6000 operations (DC resistive; AC at .75 to .80 pf)
3. Temperature rise of contacts 30˚ max. at maximum continuous current rating
4. Dielectric Voltage Withstand UL- 2200V rms
5. Spacings (between live parts or live parts to ground) UL – 0-250V (3⁄64 in. min.) 251-600V (1⁄8 in. min.)
