HEAVY DUTY SWITCH

A multipole heavy duty manually or remote control operated switch is constructed of individual pole units stacked side-by-side. Each pole unit includes first and second molded insulating members joined side to side to form a housing having a chamber, and both stationay contacts and an arc chute are within said chamber. A so-called four-bar linkage connects the switch arms to a bail connected to a common operating mechanism. When the switch is open, the movable contact ends of the switch arms extend beyond the confines of the pole unit housings to provide a positive visual indication that the switch is open. Each switch arm is constructed of two abutting sheet metal members having oppositely extending formations providing contact areas and an area for making a mechanical connection to the operating bail.
