Abstract

a. L'invention concerne un interrupteur à touche pour l'établissement et la coupure d'une liaison électrique, comportant au moins une membrane d'actionnement montée sur la face frontale de l'interrupteur et au moins deux contacts de commutation disposés au-dessous. b. Cet interrupteur est caractérisé en ce que la membrane d'actionnement est constituée par une zone relativement mince d'un élément de boîtier à paroi plus épaisse, zone bombée vers le haut et pourvue en son centre d'un appendice pénétrant à l'intérieur de l'interrupteur et sous l'extrémité duquel est prévu un contact de commutation à flexion élastique, qui coopère avec un contre-contact fixe pour le déclenchement d'un processus de commutation. L'invention est applicable notamment à l'équipement des véhicules automobiles.at. The invention relates to a push-button switch for establishing and disconnecting an electrical connection, comprising at least one actuating membrane mounted on the front face of the switch and at least two switching contacts arranged below. b. This switch is characterized in that the actuating diaphragm is formed by a relatively thin zone of a housing element with a thicker wall, the zone convex upwards and provided at its center with an appendage penetrating inside the the switch and at the end of which a resiliently bending switching contact is provided, which cooperates with a fixed counter-contact to initiate a switching process. The invention is particularly applicable to the equipment of motor vehicles.
