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.
