Claims

[Scope of utility model registration request]

A device sensor comprising a proximity switch consisting of a reed switch and a magnet, and an actuator consisting of a magnetic member that rotates depending on the presence or absence of an object to be measured and moves in and out between the reed switch and the magnet of the proximity switch. , a yoke is not attached to the magnet so that the magnetic flux exits outside the proximity switch, and a portion of the actuator corresponding to the proximity switch is made U-shaped, and the magnet is sandwiched between the U-shaped portion. 1. A position sensor, characterized in that the actuator is configured to be inserted into the magnet so that the actuator is not attracted by the magnetic force of the magnet.
