１に記載のシヨツクレス形電磁操作切換弁。[Claims for Utility Model Registration] 1. The end face of a spool of a switching valve supported by a spring is pressed against the spring by a push rod integrated with a movable iron core that is attracted by the excitation of a solenoid provided on a fixed iron core. A shortless type electromagnetically operated switching valve characterized in that the spool is provided with a shim that prevents the fixed iron core and the movable iron core from coming into close contact with each other in the valve that applies a stroke to the spool. 2. The shortless type electromagnetically operated switching valve according to claim 1, wherein the shim is made of a non-magnetic material and is provided at a contact portion between the movable iron core and the fixed iron core. 3. The shockless type electromagnetically operated switching valve according to claim 1, wherein the shim is interposed between the stroke front end of the spool and the valve housing.
