ABSTRACT OF THE DISCLOSURE An improved switch for a high-voltage device in which ignition of a power cartridge generates pressure at one end of an insulative piston to move the piston, located in a conductive member, into a passageway in an insulative liner said piston moving a contact through the passageway and away from the conductive member to break an electrical interconnection between the conductive member and the movable contact, an insulative lip seal located in the bore between the power cartridge and the one end of the piston, the lip seal being movable with the piston and being conformally force-fit into the bore, and means limiting movement of the lip seal through the bore so that the lip seal remains in the bore after the switch is open restricting the flow of the ignition products of the power cartridge.
