Overview
Micro Switch HM Series hermetically sealed basic switches contain contacts in a sealed chamber. A gas tight seal is maintained while transmitting force and motion to the switch mechanism through a metal diaphragm. HM Series Hermetically Sealed Switches are not generally recommended for 115 VAC, 60 Hz. If you have a 60 Hz application in the mA range, or applications that require the switch to function electrically during exposure to sub freezing temperatures, contact us for special design variations that are available.
