Abstract
A high-current, low-voltage load-break switch of the type having a plurality of fixed contacts and a plurality of movable contacts. Each of the movable contacts moves between a closed position in bolted pressure contact with one of the fixed contacts and a open position which is displaced from its fixed contact. An actuating bar connects the movable contacts for movement of the contacts in unison. A switch-operator mechanism is provided for rapidly closing the switch by driving the movable contacts to their closed positions and also to their open positions. An electrically non-conductive operating rod assembly is provided for connecting the actuating bar and the switch-operator mechanism. This rod assembly includes an elongated metal rod having threads at its opposite ends. One end of the rod is threaded to a first metal yoke which is pivotally connected to one end of an insulator link. The insulator link is pivotally connected to an operating lever formed as part of the switch-operator mechanism. The opposite end of the elongated rod is threaded to a second metal yoke. The second metal yoke is pivotally connected to one end of a second insulator link. The second insulator link is …
