Abstract
An electric switch includes a base which receives a plurality of fixed electrical contacts and a movable electrical contact. The switch also includes an actuating body made of elastic material. The switch also includes a central, top, pushbutton. The body includes a lateral part, surrounding a top force-receiving portion. The pushbutton includes a lateral actuating surface for acting on this top lateral part of the body. When operated, successively, the central actuating surface of the pushbutton acts on the top force-receiving portion and elastically deforms a wall part of the body, and then the lateral actuating surface of the pushbutton acts on the top lateral part.
