<p>A key-operated electrical switch includes a rocker member which is rotatably mounted about an axle connected between two trunnions on the top of the switch casing. A carrier member is likewise mounted about the axle and has a portion which extends into the switch casing to operate the bridge mechanism for opening and closing the switch contacts. The rocker and the carrier member are free to rotate relative to one another about the axle with the carrier member moving into a cavity in the rocker. The key is inserted into the rocker and carrier to connect them together such that movement of the rocker will move the carrier in unison therewith to operate the switch.</p> |
