Title
(EN) TEMPERATURE-DEPENDENT SWITCH
(FR) COMMUTATEUR DÉPENDANT DE LA TEMPÉRATURE
Abstract
(EN) In a temperature-dependent switch (10) having a switching mechanism (11) that has a movable contact part (25), which cooperates with a stationary counter contact (24) and is moved by a spring part (26, 28) to which the movable contact part (25) is electrically conductively connected, the switching mechanism (11) produces an electrically conductive connection between the stationary counter contact (24) and a second counter contact in a temperature-dependent manner. The switch is provided with an arc-shielding plate (38), which is devoid of mechanical function, is arranged on an upper surface (37) of the spring part (26, 28) and covers sections thereof.
(FR) La présente invention concerne un commutateur dépendant de la température (10) comportant un mécanisme de commutation (11) comprenant une partie contact mobile (25), qui coopère avec un contre-contact fixe (24) et qui est déplacée au moyen d'une partie ressort (26, 28) à laquelle est connectée de manière électriquement conductrice la partie de contact mobile (25), le mécanisme de commutation (11) produisant une connexion électriquement conductrice entre le contre-contact fixe (24) et un second contre-contact d'une manière dépendant de la température. Le commutateur est pourvu d'une plaque de protection (38) contre les arcs, qui est dépourvue de fonction mécanique, agencée sur une surface supérieure (37) de la partie ressort (26, 28) et recouvrant des sections associées.
