Abstract

Electrical interlock for domestic appliances, partic. washing and dishwashing machines and which cannot be defeated with mechanical means is formed by a contactless control device which trips the mains supply when, e.g. a door is opened. Device includes an inductively operating control member one part of which is attached to the door and another part is attached to the frame, the opening and closing of the door producing different electrical signals, which are applied to an evaluting circuit which induces stripping or closing of the mains supply. Control member may be formed by a pulse generator or by a permanent magnet which is associated with an induction coil.
