ABSTRACT:
An electrical switch which is mainly adapted for household electrical appliances is made of a hollow main body in which a push-button can slide from top to bottom and from bottom to top. The lower portion of the push-button supports two lugs maintaining the blades carrying the mobile terminals cooperating with studs rigidly connected to square-pieces fixed on the bottom of the main body. The lugs carry laterally a hollow heart-shaped cam in which can circulate a dog fixed to the upper portion of a rock-piece pivotally mounted on a pin rigidly connected to the inner wall of the body, thereby allowing opening and closing of at least one electrical circuit by the switch.
