SOR’s hermetically sealed Big Hermet explosion-proof pressure switch is designed for mounting in a panel or on the wall when easy access is important. The pressure-sensing assembly of the Big Hermet is identical to a conventional static O-ring type switch with the exception that the switching element assembly is hermetically sealed in a steel capsule. This versatile pressure snap switch works in a wide variety of environments and industrial applications and is available with the maximum explosion-proof rating.
