Abstract
A steering column switch for a vehicle includes a switching lever that operates by pivoting in relation to a housing. The lever has a locking pin which assumes a stable position on a switching gate when the lever is not operated and is guided into an unstable position by operation of the lever. The switching gate guides the pin back into the stable position when operation of the lever ceases. A permanent magnet on a body of the lever is brought against an electromagnet on the housing by pivoting the lever into the unstable position. The lever is held in the unstable position by magnetic attraction between the magnets for a time in which a function associated with the lever being actuated into the unstable position is active. Afterwards, the electromagnet produces a counter magnetic field which interrupts the magnetic attraction so that the lever returns to the stable position.
