Open Frame Instrument Switches

Cole's Open Frame Instrument Quality Rotary Switches provide low contact resistance (.005W), very high contact reliability (a bifurcated brush means 100% redundancey to avoid contact failure), smooth action with positive positioning, precision design, and trouble-free construction of glass epoxy insulators and silver conductors.

Designed and manufactured to meet or exceed applicable sections of Military Specifications:

MIL S 3786
MIL T 945 QQ-P416
MIL S 13282
MIL STD 202
MIL A 8625
MIL STD 167

All Open Frame Series Switches are available pre-wired to terminal boards. When ordering, specify the locations of terminal boards as viewed from shaft ends such as: (top) or (left and top) (left, top and right) or terminal boards can be mounted on all four sides of each deck. Switches can be furnished pre-wired to connectors mounted in same manner.

Cole's Open Frame Instrument Rotary Switch are Uniquely capable for High Voltage, High Current, and Low Resistance applications. The dielectric and conductive materials used are such that the switch performs like a high quality conductive wire between the pole and the contact when the switch is in position. The switch is rated for 100,000 cycles minimum. The contact mechanism is a bifurcated brush making it 100% redundant, for reliability in demanding switching conditions.

The Cole Open Frame Rotary Switch can be used on Electrical Test Equipment such as Low Voltage Signal Testing or Solid State Testing to eliminated transients. The switch can provide power to generators, receivers, transmitters, etc.

Multiple decks can be used to provide binary coded output.
