Index switches
Heavy-Duty Temperature Switches
A mechanical temperature switch turns something on or off at a set temperature. Index switches add tight tolerances, fast response and specifiable reset points – proven on millions of engines and vehicles.

How it works
How It Works
Two Snap-Action Elements
A pressure (or temperature) disc snaps over at the set point and triggers a Honeywell MicroSwitch™ – two snap-action elements in series. The result is clean, chatter-free switching that shrugs off vibration and lasts up to a million cycles or more, depending on load and voltage.
