53 CONSTRUCTION DETAILS DETENTACTION SWITCHES Electroswitch Detent Switches Electroswitch Detent Switches are a heavyduty 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 shows a cutaway view exposing the basic components. Figure The Contact Deck Assembly The 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, maintenancefree operation results from the doublesided, doublewiping, selfcleaning knifeblade moveable contacts. Overview The mounting plate () connects a detent assembly () to one or more contact decks () and finally a position limiting stop plate (). These assemblies are bolted together along with a steel shaft () and a handle (). The Electrical Design The Detent Switch contacts operate on the time proven reliable principle of knife switches doublesided, doublewiping, springwiper blades closing on both sides of a terminal. This design is shockproof and virtually bounceproof. Figure shows a typical contacting arrangement. Figure The Detent Assembly The detent assembly contains a specially designed star wheel and up to four springloaded ball bearings providing snappy positive indexing. Spring return switches use a coil spring in place of the star wheel/spring/ball bearing arrangement. The PulltoLock Mechanism Control switches generally have positions both left and right of the normal vertical position. The handle springreturns to the normal position. The pulltolock 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 inadvertently closing a circuitbreaker when it is desired that it stay in the tripped position. The barrier next to the stationary terminals is clearly marked with numerals for and 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, illustrated in this catalog, simplifying field wiring. All you need to do is connect the instrument leads and the line wires. The Stop Plate The 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.

54 CONSTRUCTION DETAILS SNApACTION SWITCHES SnapAction Switches SnapAction 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, 0, 0, and 00 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. Stationary Contacts Nonshorting (breakbeforemake) contacts are standard in all the ratings and circuits shown in this catalog. Shorting (makebeforebreak) contacts, required in some special circuits, are available on order. The sweep contact maintains the connection with the rotor through consecutive positions. The Electrical System The electrical system comprises two or more stationary contacts (9) and one or more sets of movable contacts. These are pairs of springmetal blades () that make highpressure, lowresistance contact on both faces of the stationary contacts while bridging two or more of these contacts. The stationary contacts fit in radial grooves () in the rim of molded insulating disks (), within which the movable contacts are carried on an insulated shaft (). All making and breaking of electric circuits takes place within the closed spaces between adjacent disks. Their quickbreak action makes these switches particularly suitable for directcurrent service. The ends of the stationary contacts extend outside the insulating disks and serve as connecting terminals (0 ). This onepiece contact/terminal construction minimizes series resistance and heating. Depending on current rating and onwiring requirements, the terminals may have tapped holes for connecting screws or clearance holes for bolt connection of cablelugs. The Mechanical System The mechanical system is designed to provide uniform highspeed make and break, regardless of whether the operating handle () is turned rapidly or slowly. Turning the handle through approximately 0 in either direction winds a powerful coil spring (). When this is fully wound, the indexing plate () is momentarily withdrawn from the locking plate () by an eccentric cam. The driveshaft and movable contacts then snap rapidly to the next position. The indexing plate holds them until the springdrive mechanism is again operated. Transit time is about ten milliseconds. Assembly The snapdrive mechanism, mechanismcover (), locking plate, mounting bracket (), insulating disks, and back plate () are stacked on side securing rods () and bolted firmly together to form a rigid assembly. The handle is keyed to the operating shaft and secured by a screw. Moveable Contacts (Rotors) The simple, straightacross rotor bridges stationary contacts in the same insulating disk. It provides singlethrow switching in Circuit and doublethrow switching in Circuit. The rightangleblade rotor provides a doublethrow switching, with an intermediate OFF position, in Circuit. A multifingered blade is combined with a singlecontact blade to form a composite (doubledeck) rotor that interconnects stationary contacts in adjacent disks. Suitable blade arrangements provide doublethrow, triplethrow, or fourthrow switching. Insulating Disks (and Circuits) The insulating disks, molded of phenolic per MILM, 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.

55 CONSTRUCTION DETAILS CAMACTION SWITCHES CamAction Switches The design principle allows the combination of a relatively small number of basic parts to satisfy a wide variety of requirements for selector and control switching in power circuits. The Mechanical Design The switch features a modular design with switching decks () stacked with a detent mechanism deck (), a mounting plate (), and a handle (). A steel shaft (0) couples the handle to the operating parts. Two steel securing rods () are used to bolt the whole mechanism rigidly together. The basic parts and assemblies are shown below. Contact Operation The 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 springloaded 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 () is springloaded () and held by the cam follower (). It makes a circuit with the two stationary contacts () when the cam follower enters the notch in the cam (). 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). The Detent Assembly The detent assembly () consists of a springloaded detent block () with a roller coming into contact with a notched detent wheel (). This detent wheel provides the standard detenting as well as optional 0, 0 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 Assembly The contact assembly () consists of a rigid thermosetting plastic housing, two sets of stationary contacts (), and two springloaded () movable contacts () held in cam followers (). Floating on the shaft and held within the contacting chamber are two independent cams (). The cams are notched to provide the contact close angles desired. The contacts are springloaded closed and mechanically opened by the cam action to avoid sticking. The terminal screw () and pressure clamp () will easily accommodate stranded wire with lugs or solid wire, either with or without lugs, compatible with switch size. 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 contact 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 0 King Avenue Weymouth, MA 0 TEL: () 00 FAX: ()

60 ELECTROSWITCH TESTING AND LIFE EXpECTANCY All About Testing Switches 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:. 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.. Test under an application oriented specification something that simulates actual operating conditions such as environment, overloads, surges, etc. UL0 on SPECIAL USE SWITCHES and CSA C. on INDUSTRIAL CONTROL EQUIPMENT for use in Ordinary (nonhazardous) Locations are probably the best specifications in widespread use. The,,, and are UL recognized and CSA certified to these specifications.. 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 conditions are outlined on the SELECTOR CHART for each type of switch. The results are summarized below: Both UL and CSA testing consists of two parts:. Product testing to the specifications.. Followup service by UL and CSA personnel at the factory, including inspection and testing 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.
