固定して成る近接スイツチ。 A detection coil housed in a ferrite core, a transmission circuit using the detection coil as a transmission element, and a detection circuit that detects the approach of a detected object according to changes in the output of the transmission circuit are incorporated into the cylindrical case. A hard plate-shaped printed circuit board is housed therein, and an end thereof is electrically connected to an external terminal of the printed circuit board, and the cable is led out to the outside through a cap that closes one side opening of the case. In the high frequency oscillation type proximity switch, the detection coil and the hard plate-shaped printed circuit board or the hard plate-shaped printed circuit board and the cable end are electrically connected by a flexible printed circuit board, and the flexible printed circuit board is soldered to the hard plate-shaped printed circuit board. When a flexible printed circuit board is soldered, it is held down and fixed to the rigid plate-shaped printed circuit board using staple fittings that have fixing protrusions on the legs that lock onto the opposite side of the rigid plate-shaped printed circuit board. Switch.
