Abstract
Magnetic microswitch able to be actuated by a magnetic field, including two strips (1, 2) each including a distal portion (5, 5') whose overlap forms an air gap of distance e, at least one of said strips (1) made of magnetic material having one end (3) attached to the substrate via a foot (9), a median portion (4) and a distal portion (5) of length L.sub.o, said strip being flexible with respect to the second strip (2). The median portion (4) of the flexible strip (1) is formed with a total cross-section less than that of the distal portion (5) so as to have a lesser bending resistance allowing the strip to have both deflection of an amplitude at least equal to e to make contact under the influence of a magnetic field and sufficient return force towards the open position in the absence of a magnetic field.
