ROTARY WAFER SWITCHES • Patented Unidex indexing • Flexible Switch package • Miliary & Commercial Version • Variety of Switching configurations • BCD & Hexa Decimal coded outputs • Optional water sealing CRISP, UNIFORM DETENTING A patented Unidex™detent, using one or two balls operating on a starwheel, gives Multidex switches a crisp, uniform feel. Unidex detents last a lifetime and are designed to meet JSS 51207 requirements. Unidex indexing is available in 10° ,15°,20° and 30° throw Both rotor and stator are moulded diallylphthalate: Thousands of variations - available in a single switch - will eliminate much tedious design work for the engineer The OAK pioneered double wiping contacts are self - cleaning. The terminals are designed for easy insertion of wire and fast soldering. Two types of Contacts - shorting (Make before break) Non Shorting - (Break before make) Silver plated brass contacts are rated for 0.5 Amps (resistive) at 28 VDC . and 0.25 Amps (resistive) at 110VAC. Silver alloy contacts are rated for 1.0 Amp(resistive) at 28 VDC. and Gold flashing or gold plating can be provided over silver alloy when specified to improve storage characteristics, dry circuit switching, increase reliability when used infrequently or in corrosive atmospheres or limit contact resistance variation:(See under Military specifications All component parts requiring plating are cadmium or zinc plated and passivated as per our standards. OPTIONS AVAILABLE Fixed stops at total number of positions specified are standard. If OFF position is required, please indicate whether it is to be the first or last switch position. Clip Terminals Standard is 60° bend on terminals. Flat and reverse clips are also available on request. Electrostatic shields, mounting brackets, etc.are available as standard and can besupplied when specified. RESIST ADVERSE ENVIRONMENTS Commercial types rated from - 25° to +85C°, military types from - 65° to + 85°C. Both types are made of materials and finishes to withstand the 50-hour salt spray MILITARY SPECIFICATIONS The Multidex switch is designed to meet the US MIL-S- 3786/R-05 requirements and is Type Approved in India switches should incorporate silver alloy (plain, gold flashed or gold plated) contacts, water sealing (both shaft and index'O' ring seals) and Stainless Steel shafts. Contact rating requirement for resistive loads as per

1. For 2 pole, 23 active position operation, circuitry will be as shown on section I. 2. As number of required positions decreases, a corresponding number of short clips will be deleted from the clockwise end of rotation. 3. For 4 pole, 11 active position operation, circuitry will be as shown on section II. 4. As number of required positions decreases, a corresponding number of short clips will be deleted from the clockwise end of rotation. This stator does not permit cilps on front and rear to be tied with common eyelet. Only odd or even positions can be used on either side of stator. If...
