ABSTRACT:
A microswitch comprising a housing, a switching tappet, connection contacts connected with fixed contacts positioned in the interior of said housing, and a contact bridge with at least one switching contact movable from a first to a second switching position by way of the switching tappet. The contact bridge is held in its first or second switching position by means of a bistable spring arrangement. The microswitch has structurally simple forced, separation means without any necessity for change in the overall size. Its switching tappet is provided with a cantilever with a holding-down device at one end which, in the first switching position of the contact bridge is arranged at a small distance from said contact bridge and which, in the second switching position, projects into the path along which the contact bridge moves.
