Claims

[Scope of utility model registration request]

A yoke 8 in the shape of an elongated flat plate made of a magnetic material, a permanent magnet 6 in the form of an elongated bar arranged so as to be magnetically attracted to the yoke 8, and an outward force acting on one end of the magnet 6 in a direction in which it separates from the yoke 8. and a reed switch 4 disposed on the opposite side of the magnet 6 from the yoke 8 at a distance from the magnet 6 by a distance corresponding to the movement distance of the magnet 6 which is moved by the action of the external force. , the knob 7
A micro-switch mechanism is constructed in which the tip of the micro-switch mechanism is housed in a housing 1 made of a non-magnetic material with its tip protruding outward from a through-hole 2.
