Abstract

A safety switch device for an apparatus, having a door for sealing the treatment space of the apparatus, has a switching means which returns to a breaking position when the door is opened, thus preventing start or operation of the apparatus. The switch device has an operating means (8) and, cooperating with it, a locking means (26, 27) having a locking position for locking the switching means in the breaking position (Fig. 3). When the door is opened, the locking means is displaced to its locking position and prevents switching the switch device. Also disclosed is a microwave oven equipped with such a safety switch device, as well as the use of one or more such safety switch devices in door-equipped household appliances. <IMAGE>
