Title: Electrical interrupter switch

Abstract: An electrical disconnect switch and circuit interrupter has an interrupter with an elongate tubular housing assembly that mounts on a fixed contact structure of the switch and has an internal fixed interrupter contact electrically connected to said fixed contact structure. A movable interrupter contact that normally abuts the fixed interrupter contact has a conductive actuating rod that slides in an apertured plug in one end of the housing assembly and has an actuating catch at its outer end, and a fixed conductive catch on the housing is electrically connected to the rod through the plug. An operating arm on a pivoted movable contact structure of the switch engages the catches sequentially as it is moved from closed position, first completing a bypass circuit through the fixed catch and then pulling the actuating rod to separate the interrupter contacts. The arm ultimately rides off the actuating catch and a spring returns the movable interrupter contact to its normal position.
