ABSTRACT:
A high tension vacuum switch, comprising two relatively axially movable switching contacts and two annular electrodes for shielding the open contacts from excessive electric field, in which each shield is associated and electrically coupled with a respective one of said switching contacts and projects slightly beyond the contact surface of said contact in the direction towards the other switching contact to provide the field-shielding effect when the contacts are open. At least one of the shielding electrodes is not directly connected electrically but is only capacitively coupled with its respective switching contact so as to add the advantage of much smaller overall dimensions for a switch of this kind.
