Abstract
The invention relates to a switch provided with self-cleaning contacts used, in particular for actuating a horn for a steering wheel of a motor vehicle. The inventive switch comprises at least two opposite contacts one of which is movable and touches the opposite contact by means of an actuating element. The self-cleaning of the contacts is carried out by the reciprocal sliding thereof, the contact associated with the actuating element is fixed to a supporting element which is embodied in such a way that it is elastic and fixed to an end, an opposite end being free and moveable. Said invention is characterized in that the supporting element from the fixing side outward has an inclined line with respect to the direction of actuation in the direction of said actuating element, and subsequently in the direction of the free end thereof. A line is also inclined in the direction of the free end thereof with respect to the direction of actuation starting from the actuating element.
