MICRO SWITCH Sealed and High Accuracy Switch Line Guide extreme conditions. The hermetically sealed lineup includes Engineered smarter. Basically better. Honeywell Sensing switches that maintain the contact in a gas-tight seal, while and Control (S&C) offers an impressive collection of transmitting force and motion to the mechanism through a environmentally sealed limit switches and basic switches, metal diaphragm. And our high-temperature products have as well as hermetically sealed products. Many of our the switching element mounted on a ceramic base with environmentall sealed limit switches incorporate the gold stainless steel enclosures. standard of basic switches the MICRO SWITCH SM/SX Series resulting in enhanced accuracy and reliability under most Honeywell S&Cs flexible sealed switch line opens the door to new, powerful possibilities for your applications.
