Abstract

Thermostat remplissant deux fonctions : celle d'un thermostat proprement dit avec déclenchements et réenclenchements successifs, et celle d'un rupteur de sécurité sans réenclenchement automatique. L'extrémité d'une lame élastique de contact 2 est fixée par un rivet 3 sur un isolant 1, en même temps que des raccordements électriques 6 et 7. La lame 2 porte un contact 4 se déplaçant en face d'un contact fixe 5, ainsi qu'une cheville de centrage 8. Deux bilames circulaires 10 et 16, centrées par la cheville 8, sont placées de part et d'autre de la lame 2. Le sens de la convexité des deux bilames change pour deux températures différentes, en soulevant la lame 2. La bilame qui réagit à la température la plus élevée ne revient pas automatiquement en arrière, même quand la température redescend, et elle laisse le contact ouvert.Thermostat fulfilling two functions: that of a thermostat proper with successive tripping and reclosing, and that of a safety switch without automatic reclosing. The end of an elastic contact blade 2 is fixed by a rivet 3 on an insulator 1, at the same time as electrical connections 6 and 7. The blade 2 carries a contact 4 moving opposite a fixed contact 5 , as well as a centering pin 8. Two circular bimetallic strips 10 and 16, centered by the pin 8, are placed on either side of the blade 2. The direction of the convexity of the two bimetallic strips changes for two different temperatures, by lifting the blade 2. The bimetallic strip which reacts to the highest temperature does not automatically come back, even when the temperature drops, and it leaves the contact open.
