Electric switch

In an electrical switch having a single-piece contact element pivoted about a middle contact block and made of electrically-conductive material, said contact element being brought selectively into or out of contact with stationary contact blocks in two switch positions by means of an actuating element, wherein the contact element simultaneously serves to produce a snap action movement, the improvement comprising said contact element comprising a contact spring formed approximately in the shape of a triangle and open at one apex of the triangle, said contact spring having a bearing in the center of the side thereof opposite the open apex for engaging said middle contact block, a second side of the contact spring, in a first switch position, bearing under spring tension against one stationary contact block disposed on one side of the middle contact block, a third side of the contact spring, in a second switch position, bearing under spring tension against another stationary contact block disposed on another side of the middle contact block, said actuating element having a recess therein, the free ends of the second and third sides of the contact spring, at the open apex thereof, engaging in said recess.
