Device for actuating an electrical contactor
First Claim
1. A device comprising an electrical contactor on a vehicle steering wheel and an actuator arranged to be movable to a limited degree relative to said steering wheel in a direction corresponding to a steering wheel axis against a return bias, said actuator being connected to a component of said steering wheel via webs reversibly and resiliently deflectable transversely to said steering wheel axis in response to axial pressure acting on said actuator, said webs in the deflected state actuating said contactor, thereby providing an electrical contact.

Abstract
A horn switch on a vehicle includes an actuator (1) connected to the steering wheel via webs (2) resiliently deflectable transversely to said steering wheel axis. The actuator is normally spaced from a contact foil and, when actuated, urges on the contact foil to establish an electrical contact between opposed contact areas of the foil.
