Abstract

An electric switch comprises a first normally open contact bridge 11 for bridging a first pair of fixed contacts 7,8, a second normally closed contact bridge 12 for briding a second pair of contacts 27,28 and a reciprocable stem 3 movable by snap action against the bias of resilient means to simultaneously move the contact bridges 11,12 and to move by its inner end 47 the second pair of contacts 27,28, each of which is mounted on a bent resilient contact blade 29,30 which is biased against a fixed stop 41,42 when in the closed position. <IMAGE>
