Abstract

1. Protection switch for an electric installation comprising, in an insulating case (11) : - at least one fixed contact (C2) and a mobile contact (C1) which cooperate and form a current path which can be interrupted in response : - either to the actuation of a magnetic (DM) and/or thermal (DT) automatic tripping member, - or to the actuation of a manuel tripping and resetting control member (M), - a lock comprising : - a hook (12) which can be moved by the automatic tripping member (DM, DT), - a tripping lever (18) having at a first end a nose-piece (22) cooperating with the hook (12) and connected to the manuel control member (M) so as to pivot, either by bearing on the hook (12) so as to cause voluntary opening of the contacts or on a mowable shaft (19) connected to the manual control member (M) for causing automatic tripping ; this tripping lever (18) being connected to a contact piece (32) mounted for pivoting on a pin (30a) belonging to a rigid conducting piece (30) fixed with respect to the case (11) and fast with a terminal (B1) of the switch, by means of a spring (R) forming a resilient transmission link between the lever (18) and the contact piece (32) and contributing to sudden opening of the contact piece (32) characterized in that the resilient link (R) consists of a hairpin spring in the shape of a V, a first leg (28) of which is applied to a second end of the tripping lever (18) and the other leg (29) of which cooperates with two rests situated on each side of the pin (30a), namely an opening rest (36) and a closure rest (31).
