ABSTRACT:
An electric signals supplying device in a solenoid valve, wherein two solenoid coils are provided for operating respective valve members, is disclosed. This electric signals supplying device has a socket which has four conducting pins in total, including two conducting pins connected to a terminal on one of the polarities of the two solenoid coils and constituting a first pair, and two conducting pins connected to a terminal on the other of the polarities and constituting a second pair. A connector detachably provided on the said socket is detachably provided with four contacts in correspondence with the four conducting pins. The two conducting pins connected to the terminal on one of the polarities and constituting the first pair are electrically connected to each other through a short circuit member. The two conducting pins connected to the terminal on the other of the polarities and constituting the second pair are connected to a contact connecting signal cables respectively. One of the two conducting pins constituting the first pair is connected to a contact connecting a common signal cable. The polarity of a control signal is changed by exchanging the positions of the short circuit member 45.
