  • Reversing device with electromagnetic control and mechanical locking
    Patent number: 4506245
    Abstract: Reversing contactor with mechanical locking. The casing (2) of the device includes a half-casing (3) to which are coupled two identical covers (70, 71), each of which closes one of two housings (9, 10), each of which receives the fixed and movable pieces of an electromagnet and the corresponding sets of contacts (49, 50). Such a contactor, which lends itself especially well to compact production, is used to change the direction of a motor with every guarantee of safety.

  • Small contactor with a removable subset of auxiliary switches
    Patent number: 4485365
    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.
