Abstract
In a manually actuated on-off switch with electromagnetic release, a component part (9) opening and closing the switch contacts and an actuating member, in particular a rotary control grip (2), are designed as separate parts and for being coupled, noting that the component part (9) opening and closing the switch contacts is loaded by a spring in direction out of the take-along position for the closing movement. The component part (9) and the actuating member (2,6) are at least at their mutually facing front surfaces or, respectively, engaging surfaces (7a, 8a) formed of a material being conductive for the magnetic flux and are designed for being coupled one with the other in a force-locking manner by means of the electromagnet. The coil (10) of the electromagnet is, in this case, preferably arranged for being put to voltage via auxiliary contacts (16).
