Abstract: A compressed gas electrical switch wherein the switching point, i.e. the contact actuating mechanism is operated by means including a pivotally mounted lever which is introduced into the pressure-gas filled switch housing. For sealing the lever at the point of entry into the switch housing, the lever is surrounded partially by a sleeve connected to it and which is provided at the entry point with a spherically shaped zone. A highly elastic sealing gasket rests upon the outer surface of the sleeve, one end of the gasket including a connected flange at one end situated on the spherically shaped zone of the sleeve, and the other end of the gasket being secured to the end of the sleeve within a disc-shaped part connected in a gas-tight manner to the lever.
