The LC series switch assembly is designed to provide reliable operation in extreme environments. This switch is used in various applications on commercial jetliners. Available in leaf and roller leaf configurations these assemblies incorporate HSI’s 6300 series hermetically sealed switch.

The switch has an extremely low leak rate of 1x10-8 atm. cc/sec., assuring a controlled environment for maximum electrical life. The metal corrosion resistant housing withstands most media and allows immersion of the switch in fluids such as synthetic hydraulic oils and jet fuels. Even when the assembly is operated in extreme temperatures and pressures the switch mechanism operates in a contaminant free environment filled with inert gas.
Fine silver, platinum and gold contacts are available to meet various temperature and current requirements. HSI’s engineering group is ready to assist you with your application requirements including customized assemblies.
