<p>Switch comprising an electromagnet (3, 5) equipped with a tiltable moving armature (7) extended so as to form a lever (9) bearing at its end a moving contact (15) which can be displaced relative to a fixed contact (17), the opening and/or closing movements of the contact being controlled by the electromagnet (3) and by a return spring (23) characterised in that the lever (9), integral with the moving armature (7), is arranged tiltably on a rotational axis (11) disposed so that the two arms of the lever disposed on either side of the point of rotation (11) are balanced from the point of view of the masses. <IMAGE></p> |
