Abstract
In a solenoid valve with ON/OFF switch arranged by a valve member and the associated valve seat defined in an electrically conductive body, the solenoid valve has a stopper connected to the valve member for setting the stroke of the valve member and is guided by an insulating guide member mounted on the body in such a way that the stopper comes in contact with only one of the end portions of the guide member when the solenoid actuator is in the de-energized state and this end portion is acting as an electrically insulating stopping member for the stopper.
