- 9 - ABSTRACT A tappet , in particular for cooperating with camshafts in electrical changeover switches, circuit breakers or the like, comprises a body provided with a cavity opening into two opposing faces of said body and containing, mobile against a spring, a generally flat contact element the opposing free ends of which project from said cavity and from said body so as to cooperate with fixed contacts generally arranged to the sides of said body and rigid with the casing of the changeover switch or the like. The mobile contact is subjected to the action of an element or slider mobile within said cavity and arranged to cooperate with the cams of a usual camshaft. According to the invention, said slider comprises projecting elements slidable in a guided manner in guide slots or tracks provided in the body of the tappet during its movement within the recess of this latter, with consequent displacement of the mobile contact from an inoperative position to a working position in which it cooperates with the fixed contacts of the changeover switch or the like, said mobile contact rocking relative to said slider by rotating about an axis on being displaced from its working position.
