Evolution of Honeywell Thermal Switch

From the first product, a windshield temperature control thermal switch in 1947 to the 700 Series Thermal Switches on board Mars Rover.

150 Series Thermal Switches

The 150 Series harnesses the electrical capability of a micro-switch and the thermal capability of a bimetal switch in one device.

250 Series Thermal Switches

Snap-action thermal switches specifically designed for applications requiring more than 5 amperes at 28VDC resistive in a robust hermetic package.

270 Series Thermal Switches

High-current, high-reliability switches for space applications.

500 Series Thermal Switches

Combines small size with robust electrical characteristics, packaged for severe environments with flexible mountings.

700 Series Thermal Switches

High reliability space-qualified thermal switches designed to support manned and unmanned space applications.

Locomotive Train Switches

Specifically designed and qualified to operate the cooling fan contactor on General Motors Electro-Motive Division (EMD) locomotive engines.

F-15 Eagle

Aircraft Spares

Honeywell continues to build switches and sensors for use on commercial and military aircraft that are long out of production but still flying today.
