ABSTRACT:
A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece. The pieces are configured and arranged relative to one another so that during the closing of the switch the countercontacts contact the contacts after the primary contact pieces are moved to the second position and before they are moved to the third position, and during the opening of the switch the countercontacts separate from the contacts after the primary contact pieces are moved to the second position and before they are moved to the first position.
