ABSTRACT:
The present invention relates to a control device (1, 1′) of an electrical circuit comprising:a microswitch (2, 2′) comprising a moving element that can be driven by magnetic effect between a first stable state and a second stable state to control the electrical circuit,a fixed permanent magnet (10, 10′),a moving permanent magnet (11, 11′) that can be actuated between a first position, in which it forms, with the fixed permanent magnet (10, 10′), a substantially uniform permanent magnetic field (B0) holding the moving element in the first state or the second state, and a second position in which it is able to control the switchover of the moving element from one state to the other,an excitation coil (4) able to create a temporary magnetic field (Bb) able to cause the moving element to switch over from one state to the other when the moving permanent magnet (11, 11′) is in the first position.
