Electrical switch with current monitoring

Abstract

An electrical switch having a transmission linkage which is actuated by a rocker and which is coupled to a slide bearing contacts and which contains a triggering lever cooperating with a latching piece. The technical problem is to provide a switch with a strong latching force and reliable unlatching. The transmission linkage is constructed as a toggle lever, to the toggle joint (13) of which the rocker (14) is coupled and the first lever (12) of which is coupled in a bearing which is fixed to the housing and the second lever (11) of which is constructed as a latching lever for a pivot lever (10), which latching lever is active in a position of the toggle lever above the dead center. The pivot lever (10) engages into the slide (6). A yoke lever (15) is constructed as a triggering lever for the second lever (11) of the toggle lever and as a counterbearing for a pressure spring (26). The latching piece latches the yoke lever mechanically or electromagnetically, and the pressure spring (26) on the one hand pre-tensions in the switched-off position the slide (6) and the pivot lever (10) coupled thereto and on the other hand supplies the tensioning force for the yoke lever (15) to trigger the switch.
