Abstract

Zur gleichzeitigen Steuerung bzw. Regelung und Überwachung von Elektrogeräten, insbesondere elektrischen Strahlungs-Kocheinheiten, wird ein integriertes Steuer- und Überwachungsgerät (11) geschaffen, das einen Schnappschalter (26) enthält, der sowohl von einem thermischen Ausdehnungsfühler (13) in Form eines Stabfühlers als auch von einem elektromagnetischen Betätigungsorgan (32) in Form eines Elektromagneten (33) mit Klappanker (34) betätigt werden kann. Durch die an unterschiedlichen Stellen an der Schnappfeder angreifenden Betätigungsorgane unterschiedlicher Art und Wirkung erhält der mit nur einem Kontakt arbeitende Schalter die volle Sicherungsfunktion zweier in Reihe arbeitender Schalter. Das Gerät kann unmittelbar an dem Elektrogerät angebracht werden und wird lediglich über eine Steuerleitung angesteuert.

Figure 00000001
For the simultaneous control or regulation and monitoring of electrical devices, in particular electrical radiation cooking units, an integrated control and monitoring device (11) is created which contains a snap switch (26) which is operated both by a thermal expansion sensor (13) in the form of a rod sensor and can also be actuated by an electromagnetic actuator (32) in the form of an electromagnet (33) with a hinged armature (34). Due to the actuating elements of different types and effects acting on the snap spring at different points, the switch operating with only one contact receives the full safety function of two switches operating in series. The device can be attached directly to the electrical device and is only controlled via a control line.
