Claim:
A microswitch ( 1 ) comprising a housing ( 2 ), a switching plunger ( 4 ) arranged in displaced relationship with the centre of said housing ( 2 ) and projecting from said housing, contacts ( 22 , 23 , 24 ) arranged on the housing side located opposite the switching plunger, and a contact bridge ( 13 ) which is adapted to be transferred from a first to a second switching position through the switching plunger ( 4 ) and a bistable spring ( 14 ), said switching plunger ( 4 ) being provided with a cantilevered arm ( 9 ) which projects on one side and on the projecting end of which a downholder ( 10 ) is provided for positive opening of the contact bridge ( 13 ), characterized in that on the switching plunger side located opposite the cantilevered arm ( 9 ), a support projection is arranged, which acts on a resilient part of the spring ( 14 ) in spaced relationship with the switching plunger ( 4 ), in such a way that, when the switching plunger ( 4 ) is pressed down, a moment (M) will be applied via the support projection ( 12 ) to the cantilevered arm ( 9 ) of the switching plunger ( 4 ) in the opening direction of the contact bridge ( 13 ).
