An optomagnetic switch has a base (1) traversed by a light ray path (4, 5), a guide slit (6) which intersects said path, a movable shutter (24) which can be moved, at least partially, in said guide slit (6) between a position in which it allows the light to travel along said path and a position in which it closes off this passage, and a spring (22) for return of the shutter. Said shutter (24) and said spring (22) constitute parts of a deformable blade (2). One end of the spring (22) is attached to the base, and the movable part of said blade has a surface large enough to form a head capable of responding to a magnetic attraction exerted on the action of said spring. |
