MICRO SWITCH™ Sealed and High Accuracy Switches Line Guide

Engineered smarter. Basically better. Honeywell offers environmentally sealed limit switches and basic switches and toggle switches, as well as hermetically sealed products. Many of our environmentally sealed limit switches incorporate MICRO SWITCH™ SM/SX series components — resulting in enhanced accuracy and reliability under most extreme conditions.

The hermetically sealed lineup includes switches that maintain the contact in a gas-tight seal, while transmitting force and motion to the mechanism through a metal diaphragm. And our high-temperature products have the switching element mounted on a ceramic base with stainless steel enclosures.

Honeywell S&C's flexible sealed switch line opens the door to new, powerful possibilities for your applications.
