Claims

[Scope of Claim for Utility Model Registration] ■ In a solenoid valve that opens and closes a plurality of fluid passages opened in a valve chamber by displacing a passage switching member by energizing and de-energizing an electromagnetic coil, one end is attached to the wall of the valve chamber and a free an elastic tongue-like member having a sloped portion at the end and capable of moving the passage switching member;
The valve chamber wall is movably supported, the inner end on the valve chamber side has a slope portion that engages with the slope portion of the tongue member, and the outer end allows manual operation of the tongue member. What is claimed is: 1. A manual switching device for a solenoid valve, characterized in that it is equipped with an operating member that enables the switching of a solenoid valve. 2. The operating member is pressed in the direction of the valve chamber by a spring pressure intermediate between high pressure and low pressure generated in the valve chamber, and the valve chamber pressure during steady operation of the solenoid valve is displayed depending on the position of the operating member. A manual switching device for a solenoid valve according to claim 1 of the utility model registration claim.
