Snap-action electrical switch and assembly

摘要

The electrical switch has fixed contacts (7) with a separating gap in which movable contacts (4) mounted at the end of a carrier arm are located. The other end of the carrier arm locates in a V-groove in a block (12) fixed to a base. The carrier is retained by a tensioning spring (21) secured at the other end to a pivot mounted lever (13). When the lever is displaced by operation of a push button (14). The line of force of the spring is displaced such that the contact carrier moves from one contact position to the other with a snap action.
