DEVICE ENABLING A MASTER APPARATUS TO ACTIVATE AUTOMATICALLY AT LEAST A SLAVE APPARATUS WHEN THE MASTER APPARATUS IS OPERATED

摘要

The invention concerns a device enabling a master apparatus to activate automatically at least a slave apparatus when the master apparatus is operated. Said device is characterised in that it comprises an electrolytic capacitor (9) connected in series in the circuit powering the master apparatus and capable of being traversed by an alternating electric current when the master apparatus is operated to supply to its terminals a secondary alternating voltage applied to a rectifier circuit (10) supplying a rectified voltage feeding a relay (15) whereof the contact (16) is closed to activate the slave apparatus. The invention is applicable for example in the field of computers.
