ABSTRACT:
An electrical apparatus is disclosed which comprises a combination of a solenoid device such as a solenoid valve, a relay or a plunger driving solenoid device and an energization control circuit which energizes the solenoid device. One end of an electrical cable is connected to the solenoid valve while the other end of the cable is connected to a connector. The electrical cable prevents the transmission of oscillations which the solenoid valve experiences to the connector. The energization control circuit is housed within the connector. The energization control circuit responds to a changing of a given switch from its on to its off condition, by energizing the electrical coil only during a given time interval. When the time interval has passed, it interrupts the energization of the electrical coil, and the energization control circuit itself is substantially disconnected from the power source.
