The safety switch has a rotary cylindrical switch insert, a lock and an intermediate lever pivoted vertically in a longitudinal or transverse plane. The lever locks the switch disc. The intermediate blocking lever for the switch is acted on by a spring that holds it in its disengaged position. The lever is moved towards its blocking position by a cam (11) or a similar device fixed to the key socket and rotating with it.
