Abstract (en)

[origin: EP0449058A2] The electrical snap-action switch, particularly a microswitch, is provided with a rocker arm (18) which supports contacts, can pivot, rests with its one end against a retaining bearing (17) and, on its other end, engages on a switching spring (19) which pulls the rocker arm against the retaining bearing. In this case, the switch has an operating element (15) which moves parts of the switching spring in order to transfer the rocker arm into its individual switching positions. In order that the operating element can carry out a relatively large movement (excess movement) than is necessary for the actual changeover switching, the operating element, which can move essentially at right angles to the switching spring longitudinal axis, has in its longitudinal direction a recess (23) which in places forms a frame around the switching spring and is bounded essentially by a stop (25, 26) which touches the switching spring in one switching position, in this case the recess is designed to be long in such a manner that the switching spring which is located in the recess is free from the stop in a relatively large movement range of the operating element. <IMAGE>
