Abstract

Il s'agit d'un commutateur de court-circuit, destiné à court-circuiter un composant électronique (13), comportant :
au moins une paire de contacts électriques (2, 3) avec un contact fixe (2) et un contact mobile (3), le commutateur étant ouvert lorsque les contacts (2, 3) de la paire sont à distance et fermé lorsque les contacts (2, 3) sont en contact électrique,
une tige de manoeuvre (5) reliée au contact mobile (3),
un élément élastique (9) couplé à la tige de manoeuvre (5) pour la déplacer en translation lorsqu'il se détend, de manière à fermer le commutateur,
un élément de libération (7) couplé à la tige de manoeuvre pour la bloquer en translation le commutateur étant ouvert, et pour maintenir comprimé l'élément élastique (9),
un sectionneur pyrotechnique (12) pourvu d'un outil de coupe (12.1) pour sectionner l'élément de libération (7).

It is a short-circuit switch, intended to bypass an electronic component (13), comprising:
at least one pair of electrical contacts (2, 3) with a fixed contact (2) and a movable contact (3), the switch being open when the contacts (2, 3) of the pair are remotely and closed when the contacts (2, 3) are in electrical contact,
an operating rod (5) connected to the movable contact (3),
an elastic element (9) coupled to the actuating rod (5) for translational movement when it relaxes, so as to close the switch,
a release member (7) coupled to the actuating rod to lock it in translation with the switch open, and to keep the elastic member (9) compressed,
a pyrotechnic disconnector (12) provided with a cutting tool (12.1) for cutting the release element (7).
