Abstract

Die Erfindung betrifft ein temperaturabhängiges Betäti­ gungselement für Schalter zur Temperaturregelung, - über­ wachung und -begrenzung bei elektrischen Haushaltsgeräten sowie anderen Geräten mit elektrischen Heizelementen, bei denen das Gesamtsystem der einzelnen Elemente, bestehend aus Einführungsöffnung (2) für das Kapillarrohr (7), Nut (5), muldenartigen Vertiefungen (3) sowie Plast- bzw. Plastfolienmembran (6) integraler Bestandteil eines Plast­ spritzteiles (1) ist, welches selbst als Griff- oder Ge­ häuseteil dient, wodurch sowohl die Bauhöhe des Betätigungs­ elementes wesentlich verringert wird als auch eine ratio­ nellere Herstellung mit einer geringen Ausschußquote ge­ währleistet wird. The invention relates to a temperature-dependent actuator supply element for switches for temperature control, - via guarding and limiting electrical household appliances as well as other devices with electrical heating elements, at which consists of the overall system of the individual elements from insertion opening (2) for the capillary tube (7), groove (5), trough-like depressions (3) and plastic or Plastic film membrane (6) integral part of a plastic injection molded part (1), which itself as a handle or Ge serves part of the housing, thereby reducing the overall height of the actuation element is significantly reduced as well as a ratio neller production with a low reject rate is guaranteed.
