換弁。[Claims for Utility Model Registration] In a switching valve in which the displacement of the spool is detected by a Hall element, the Hall element is installed between a pair of magnets arranged facing each other, and the Hall element and one of the magnets are connected to each other. A sensor yoke that moves in and out of the spool is integrated with the spool, and the sensor yoke is made of a magnetic material, and the length in the direction in which the magnet faces is different in the direction of displacement of the sensor yoke. switching valve.
