Claims

[Scope of utility model registration request]

A plunger 8 is provided at one end of the switch holder 5 so as to be movable up and down, and a reed switch 14 is provided at the other end of the holder in the axial direction of the switch holder 5. In the middle part of the holder, there is a peak 37 facing the other end of the plunger 8, and a pair of troughs 38.3 provided on both sides of this peak.
Further, one end of a coil spring 41 is engaged with one end of this cam, and the other end of this spring is engaged with the holder 5 on the other end side of the cam 32. Moreover, a magnet 51 is fixed to the cam 32 at a position offset by a predetermined distance from the fulcrum of the cam, and a resistor 16 for blocking surge current is connected in series to the reed switch 14. A push button switch is provided with a terminal portion 22 for selectively shorting the resistor 16 at a connection point with the reed switch 14.
