The contact assembly comprises two fixed contacts and a mobile contact bridge (4) actuated by a switching assembly (not shown) and urged by a spring (3). The connection between the mobile contact bridge (4) and the switching assembly (1) is provided by a magnetic compensator (5, 6) connected to the switching assembly (1) by means of a load break coupling (43, 43', 44, 44', 9) adapted so that, when the compensating forces rise above a given threshold, the magnetic compensator (5, 6) is disengaged from the switching assembly (1) and becomes inoperative. <IMAGE> |
