- This type of microswitch is for example manufactured in MEMS technology (for Micro-Electro-Mechanical System).
- FIGS. 13 to 14B An exemplary configuration of a microswitch 2 sensitive to the orientation of the field lines L is shown in FIGS. 13 to 14B.
- a microswitch 2 sensitive to the orientation of the field lines L comprises a deformable ferromagnetic movable membrane 20 which can be actuated in rotation about an axis of rotation (R) by the magnetic actuator.
- the membrane 20 is for example Fer-Nickel.
- the membrane 20 has a longitudinal axis (A) and is connected, at one of its ends, via connecting arms 22a, 22b, to one or more anchoring studs 23 integral with a substrate 3.
- the substrate 3 is, for example, the one on which the electronic chip 51 of the receiver element 5 is mounted.
- the membrane 20 is able to pivot relative to the substrate 3 along its axis (R) of rotation perpendicular to its longitudinal axis (A). .
- the linking arms 22a, 22b form an elastic connection between the membrane 20 and the anchor pad 23 and are biased during the pivoting of the membrane 20.
- the membrane At its distal end with respect to its axis of rotation, the membrane carries a movable contact 21.
- the membrane 20 can take at least two determined states, an open state (FIG. 14A) in which two fixed electric tracks 31, 32 deposited on the substrate 3 are disconnected or a closed state ( Figure 14B) in which the two tracks 31, 32 are interconnected by the movable contact 21 carried by the membrane 20 so as to close the branch of the circuit located in series or in parallel with the antenna 50 of the receiver element 5.
- One of the operating modes of the membrane 20 is to apply a magnetic field created by a permanent magnet 60.
- the ferromagnetic membrane 20 moves between its two states in alignment with the field lines L of the magnetic field generated by the permanent magnet 60.
- the magnetic field of the permanent magnet 60 has L field lines whose orientation generates a magnetic component BP 0 , BP 1 in a ferromagnetic layer of the membrane 20 along its longitudinal axis (A).
- This magnetic component BP 0 , BP 1 generated in the membrane 20 generates a magnetic torque imposing on the membrane 20 to take one of its states closed ( Figure 14B) or open ( Figure 14A).
- the permanent magnet 60 moves at the same time as the lever 1 1.
- the permanent magnet 60 is for example mounted directly on the handle 1 1 of the circuit breaker 1 or alternatively, it can also be simply mechanically secured to the lever, for example being mounted on a moving part actuated in vertical translation with each movement of the lever 1 1.

- the membrane 20 is therefore in a rest position , parallel to the substrate ( Figure 13).
- the permanent magnet 60 carried by the handle 11 has L magnetic field lines whose direction requires the membrane 20 to pass in its closed state ( Figure 14B).
- the microswitch 2 is placed in series with respect to the antenna 50 of the receiver element 5, it establishes an electromagnetic coupling between the receiver element 5 and the station 4 or if it is placed in parallel by relative to the antenna 50 of the receiver element 5, it interrupts this electromagnetic coupling between the receiver element 5 and the station 4.
- the microswitch 2 When the lever 1 1 returns to the ON position (M), the microswitch 2 is no longer under the influence of the magnetic field of the permanent magnet 60, which mechanically causes the return of the diaphragm 20 in the rest position and therefore the interruption of the electromagnetic coupling or the restoration of this coupling according to the mounting of the microswitch 2 with respect to the antenna 50 of the receiving element 5.
- the arrangement between the permanent magnet 60 and the receiver element 5 can be reversed, the receiver element 5 becoming mobile, mechanically secured to the handle 1 1 and the permanent magnet 60 fixed.

- the membrane 20 is in the open state or in the closed state in the direction of the field lines of the magnetic field generated by the fixed permanent magnet 61.
- the change of position of the handle 1 1 and therefore of the moving permanent magnet 60, d e the ON position (M) at the OFF position (A) causes a change of direction of the magnetic field lines created jointly by the movable permanent magnet 60 and the fixed permanent magnet 61 and seen by the membrane 20.
- the new direction of the L field lines seen by the membrane 20 requires him to move to its other state, closed or open.
- the membrane 20 in each of its states, is therefore controlled by magnetic effect irrespective of the position of the handle 1 1 of the circuit breaker 1.
- a single fixed permanent magnet 62 is positioned vis-à-vis the receiver element 5 to act permanently on the microswitch 2 of the receiver element 5.
- This fixed permanent magnet 62 is for example mounted on the housing 10 of the circuit breaker 1 (not visible in Figures 5 and 6).
- the lever 1 1 (for the sake of simplification, not shown in Figures 5 and 6) is likely to set in motion a movable part 7 of non-magnetic material.
- This mobile part 7 is integral with the handle 1 1 and constitutes a suitable mask, depending on the position of the handle 11, to be interposed between the permanent magnet 62 and the receiving element 5 to interrupt the magnetic effect of the permanent magnet 62 on the microswitch 2 and thus according to whether the microswitch 2 is connected in parallel or in series with respect to the antenna 50 of the receiver element 5, to establish or interrupt the electromagnetic coupling between the station 4 and the receiver element 5.

- receiving elements 5a, 5b are positioned on the housing 10, one vis-à-vis the lever 11 when it is in the ON position (M) and the other vis-à-vis the handle 11 when it is in the OFF position (A).
- These receiving elements 5a, 5b are identical to the receiving element 5 described above and can be actuated according to one of the embodiments described above. They can in particular be actuated directly by a movable permanent magnet 60 integral with the lever 11 as in FIGS.
- the station 4 in normal operation, when the lever 1 1 is in the ON (M) or OFF (A) position, the station 4 always receives a signal from one of the receiving elements 5a, 5b by electromagnetic coupling ( Figures 9 and 10).
- the receiving elements 5a, 5b store a different identifier so as to be distinguishable by the station 4.
- the lever 11 In case of electrical fault or welding between the contacts, the lever 11 is in the intermediate position (S) ( Figure 11).
