A Simple Choice for Better Performance

The basic function of a mechanical temperature switch is straightforward: Turn somthing on or off at a given temperature.

With Index Temperature Switches, you get more than the basics. We build switches to deliver improved performance and cost control for your engine, vehicle or equipment.

Efficiency from Precise Temperature Control

Chances are there are particular set and reset temperatures that are optimal for your application, where energy and operating cost efficiencies are maximized. With Index switches’ tight tolerances, fast response, and specifiable reset points, your equipment runs precisely and evenly, at just the right temperature.

Long Life and Vibration Resistance

We designed our Temperature Switches for years of service under tough, high duty-cycle conditions. Because vibration sensitivity can shorten the life of both a temp switch and your equipment, Index Temperature Control Switches put up a double line of defense against vibration with two snap-action elements. A crisp-response temperature disc triggers a Honeywell Micro Switch™, assuring clean, no-chatter electrical switching. Both elements can deliver up to a million cycles or more.
