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.Ê 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.
