摘要： The switch comprises a fixed contact (2) and a moveable contact (3) subjected to the action of a magnetic part (12). The moveable contact (3) is carried by a lever (4) pivoting about an axis (10) integral with a control member (6). The end (4a) of said lever comprises a second axis (15) which is connected to a mechanical threshold device (18), said second axis being allowed to move between a normal position maintained by the threshold device wherein the contacts (2, 3) may be closed and opened by the control member and a triggering position with respect to the threshold device wherein the lever is set in a position where the contacts are always separated. The magnetic part (12) is so positioned with respect to the pivoting lever (4) that it exerts on the latter a torque which reinforces the contact pressure before the triggering of the threshold device and which makes the lever pivot about its axis (10) in the opening direction of the contacts after triggering of said device (18). Utilization for the protection of electric installation against current overloads.
