1800 Series – Encoded

One-half inch encoded switches for direct logic level interfacing derive from the MIL-S-3786, MIL-S-22710, SERIES 1800 rotary selector switches.

Cole’s series of one-half inch encoded switches for direct logic level interfacing derive from the MIL-S-3786, MIL-S-22710, SERIES 1800 rotary selector switches, and feature the same mechanical quality as that series. The hexadecimal switch is also available in BCD, Octal, and Reflected Gray code notation, standard. Custom user codes are available on request.

Unlike other switches being introduced, the COLE 1800 series encoded switches anticipate both high-rel use, and the essentially dry circuit conditions of extremely low current switching; they offer 25,000 minimum life cycle and gold contacts – not found on most comparable units.

The switch is available in 221/2, 30, 36 and 45 degree indexing, with or without adjustable stops.

Quality construction, including materials that meet the strictest standards, allows these subminiature switches to combine high current switching capacity with constant low contact resistance. Long life and high reliability are assured by exceedingly stringent inspection and testing procedures.

1800 Series – Spring Return

The SERIES 1800 spring return mechanism is available in switches with 36¡ indexing (10 positions max) and 45¡ indexing (8 positions max).

A 1800 Spring Return Rotary Switch has a spring return mechanism which allows for momentary positions. A momentary position is active only as long as the operator holds the knob in that position; when the operator releases the knob, a spring returns the switch back to an adjacent position. This prevents the switch from remaining in a certain position when the operator lets go of the knob. This feature is available throughout COLE’s rotary switch product lines.

The SERIES 1800 spring return mechanism adds 0.160 inches to the behind panel length of the switch; all other dimensions remain unchanged.

Rotary Switches – 3900 Series

The 3900 series is designed for high and low level switching, tested per MIL-STD-202, and meets or exceeds the requirements of MIL-S-3786. Providing the ultimate mechanical and electrical reliability, the 3900 series is ideal for commercial, medical, and military applications.

IS3900 Series – Illuminated

The Series IS3900 switch offers maximum and optimum visibility at sunlight with minimum power levels. And at night, there is zero light leakage.

Cole Instrument Corporation is proud to offer a rotary switch with illumination through the end of the shaft front. This can be used to light up any part of the rotary switch’s knob. An LED (Light Emitting Diode) or an incandescent lamp is on the back end of the switch body, and a light pipe or fiber optics brings the concentrated light through the switch to the shaft front.

The Series IS3900 switch offers maximum and optimum visibility at sunlight with minimum power levels. And at night, there is zero light leakage through the length of the switch. Light can meet most chromaticity or intensity requirements. The light can be an LED or a T1 incandescent lamp.

The switch features good heat sinking capabilities, and delivers up to twice the light intensity of units at equivalent power levels. On light failure, reclamping can be done by the customer.

Cole can provide the replacement assembly. This switch can be used in airborne, shipboard, and submarine panel control displays and meets the brightness requirements of high altitude aircraft, as well as the MIL-S-901C shock requirement for submarines and ships.

IP3900 Series – Illuminated Shaft

The Series IP3900 switch offers maximum and optimum visibility at sunlight with minimum power levels. Can meet most chromaticity requirements.

Cole Instrument Corporation is proud to offer a rotary switch with illumination through the end of the shaft front. This can be used to light up any part of the rotary switch’s knob. An LED (Light Emitting Diode) or an incandescent lamp is on the back end of the switch body, and a light pipe or fiber optics brings the concentrated light through the switch to the shaft front.

The Series IP3900 switch offers maximum and optimum visibility at sunlight with minimum power levels. And at night, there is zero light leakage through the length of the switch. Light can meet most chromaticity or intensity requirements.

The light can be an LED or a T1 incandescent lamp. The switch features good heat sinking capabilities, and delivers up to twice the light intensity of units at equivalent power levels. On light failure, reclamping can be done by the customer. Cole can provide the replacement assembly.

This switch can be used in airborne, shipboard, and submarine panel control displays and meets the brightness requirements of high altitude aircraft, as well as the MIL-S-901C shock requirement for submarines and ships.

P3900 Series – PC Termination

The Cole miniature P.C. termination rotary switch is designed to provide the ultimate mechanical and electrical reliability for all applications.

Cole’s Series P3900, miniature P.C. termination rotary switch is designed to provide the ultimate mechanical and electrical reliability in instrumentation, industrial controls, medical equipment, aircraft, computers, communication, weapons, as well as ground support electronic equipment.

This P3900 Series switch is designed for high and low level switching, and to meet the requirements of MIL-S-3786 and tested per MIL-STD-202 as follows:

  • THERMAL SHOCK PER MIL-STD-202; METHOD 107, TEST CONDITION “B”
  • VIBRATION PER MIL-STD-202; METHOD 204, TEST CONDITION “B”
  • MEDIUM SHOCK PER MIL-STD-202; METHOD 213
  • HIGH SHOCK PER MIL-STD-202; METHOD 207
  • MOISTURE RESISTANCE PER MIL-STD-202; METHOD 106
  • EXPLOSION PROOF PER MIL-STD-202; METHOD 109
  • SALT SPRAY PER MIL-STD-202; METHOD 101, CONDITION “B”

The switches are available with 30, 36, and 45 degree indexing and one to six poles per deck, (see Circuit Diagram).

Unique design construction features include: all terminals on one side, self-cleaning contacts for low level switching and low contact resistance through the life of the switch (25,000 cycles min).

Hardened steel sprocket and ball bearing detent mechanism provide smooth positive detent action and a mechanical life in excess of 100,000 cycles. In the P3900, the terminals and commons are molded in diallyl phthalate thermosetting plastic sealed between decks and between the plastic and the metal terminal with a special process to eliminate flux contamination seeping inside the switch during wave soldering and/or cleaning processes.

Rotors and non-shorting rings are molded of thermo-plastic glass filled to eliminate contamination by transferring plastic particles to the contact system during the life of the switch. The P3900 switch is built in a clean atmosphere, as are all Cole products, to prevent introduction of contaminants during assembly.

These and many other quality features will provide the ultimate in mechanical and electrical reliability, during the life of the switch.
