ABSTRACT:
A switchable electrical connector for use in explosion prone environments is disclosed. The connector utilizes two pairs of electrical connectors; the first pair provides a circuit switching function while the second pair permits the removable connection of a suitable load. Sealing means are used for the first pair of electrical connectors to isolate any switching arcs from the environment. A mechanically actuated interlock is employed to prevent electrical engagement of the first pair of connectors before engagement of the second pair of connectors and to prevent disengagement of the second pair of connectors before the disengagement of the first pair of connectors.
