With over 53 years of industry experience that has produced revolutionary results, Cole answers the stringent demands of nearly all commercial, aerospace, and military applications. Into each switch produced, Cole combines imaginative engineering, quality construction, and exceptional customer service.

Illuminated Switches

Cole’s precision multi-deck switches are available with illumination through the end of the shaft front. With maximum and optimum visibility in sunlight with minimum power levels and zero light leakage at night, the quality and functionality of these switches will meet the needs of your most challenging applications.

IS3600 Series – Illuminated

The Series I-3600 switch offers maximum and optimum visibility at sunlight with minimum power levels. The light can be an LED or a T1 incandescent lamp.

Illuminated Shaft, One Inch Diameter Body

Cole Instrument Corp. is proud to offer a rotary switch with illumination at the shaft front. This can be used to light up any part of the rotary switch’s knob. A 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 I-3600 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. The 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, relamping can be done by the customer. Cole can provide the replacement assembly.

APPLICATIONS
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-901 C shock requirements for submarines and ships.
