METHOD OF MONITORING THE POSITION OF A MOVABLE PART OF AN ELECTRICAL SWITCH APPARATUS

摘要

The invention relates to a device for monitoring the position of a movable part (11) mounted on a casing (10) of an electrical switch apparatus (1), said movable part (11) being able to take at least two determined positions (M, A). The device comprises a permanent magnet (60, 62) and a reader (4) furnished with an antenna (40) for contactless exchange of data by electromagnetic coupling with a receiver element (5, 5a, 5b) associated with the electrical switch apparatus. The receiver element (5, 5a, 5b) comprises an antenna (50) controlled by a microswitch (2) switched between two states as a function of the position of the movable part (11), so as to make or break the electromagnetic coupling between the reader (4) and the receiver element (5, 5a, 5b).
