Abstract

The mechanism comprises two linkages (2,3) joined by a pivot. One of the linkages (2) is coupled at its free end by a stud guided in a rectilinear passage in the lock plate, to a rotating support for a moving contact (6). The linkage is coupled in its central pivot region, to an external operating handle (7), by a stud lodged in a curved passage (8) in the oscillating part of the control linkage. The other linkage (3) is pivoted eccentrically, at its free end, on a cam (10) mounted in rotation. The cam is retained, in the operating position, by a catch (14) with its axis of rotation coupled, through a blade, to the relay which causes the release of the circuit breaker.
