Abstract
A removable group of auxiliary switches is mounted on the upper surface (4) of the contactor housing by hinging means (28, 29) and resilient locking (32, 33) placed respectively in the area of the base (8) and of partitions (5) which separate the principal terminals (6). The group comprises two switches (make and break). Coupling in this manner makes it possible to increase the number of auxiliary switches without increasing the contactor's frontal or lateral congestion.
