Abstract

Dispositif de protection électrique Dispositif de protection électrique, comprenant : un mécanisme de commutation (10) ; un déclencheur (8), pour basculer le mécanisme de commutation en cas de défaut électrique et un voyant (15). Pour signaler un défaut électrique même si le déclencheur produit un effort faible, on prévoit un tiroir (130), mobile entre une position d’actionnement pour mettre le voyant dans une position de signalement primaire, et une position initiale pour autoriser le voyant à être mis dans une position de signalement secondaire ; un ressort de tiroir (132), tendant à déplacer le tiroir de la position initiale vers la position d’actionnement ; et un verrou (131), mobile entre une position de maintien pour maintenir le tiroir en position initiale, et une position de libération pour autoriser le déplacement du tiroir, le déclencheur déplaçant le verrou jusqu’à la position de libération en cas de défaut électrique. Figure pour l'abrégé : Figure 4Electrical protection device Electrical protection device, comprising: a switching mechanism (10); a trigger (8), to switch the switching mechanism in the event of an electrical fault and an indicator light (15). To signal an electrical fault even if the trigger produces a low effort, a drawer (130) is provided, movable between an actuation position to put the indicator in a primary signaling position, and an initial position to authorize the indicator to be placed in a secondary reporting position; a drawer spring (132), tending to move the drawer from the initial position to the actuation position; and a lock (131), movable between a holding position to maintain the drawer in the initial position, and a release position to authorize movement of the drawer, the trigger moving the lock to the release position in the event of an electrical fault . Figure for abstract: Figure 4
