摘要

The device according to the invention is provided for controlling a switch to a double contact. The switch comprises a winding of a call (a), a maintaining winding (lm), a plate of the moving contact (cm), three contact pads (x +, pc1 and pc2) and a micro - actuator is electrically controllable. The contactor has three states of operation: a first state, without electrical contact between the pads, a second state with an electrical contact between the first and second blocks (x +, pc2) and a third state with an electrical contact between the first, second and third contact stud (x +, pc1, pc2). The device comprises first means of switching transistor (t1, t2, cz2, rc1, rc3, sl) for controlling the excitation of the call winding (a) and, according to the invention, also of the second switching means having a transistor (t3, cz2, rc2) in order to activate the micro - actuator for a predetermined duration after an activation of the device.
