Remote control block with magnet system, particularly for switching on and-off motor switches and power switches

摘要

1. A remote-control block with a magnet system, particularly for successively switching ON and OFF motor-switches and power-switches in response to successive pulses of electric current flowing over an electromagnet coil, which responds to each pulse by propelling a solenoid plunger against an actuating lever on which is pivoted a dog, the dog actuating a switching rocker of the motor-switch or the like, characterised in that the pivoted dog (5) acts in alternation on each of two push-rods (8) and (9), each of which, when propelled by the dog (5), thrusts against the one or the other of the two arms (6a, 6b) of the switching rocker (6), the two push-rods (8) and (9) moving parallel to each other in alternation, so that when the one advances the other retreats ; the dog (5) being mounted pivotable between the two push-rods (8) and (9) in such a manner that with successive actuations of the electromagnet (2) the dog (5) advances first the one then the other of the two push-rods (8, 9), at the same time returning the other one to its position of rest.
