Therefore, the number of parts and the number of assembly steps are greatly reduced, so the price can be reduced significantly compared to conventional proximity switches. Since the proximity switch itself can be made extremely thin and compact, it is possible to provide the proximity switch even in a narrow space to detect objects. The present invention also allows the proximity switch to be connected directly to the printed circuit board, thereby securing the proximity switch in a predetermined position. Therefore, no members are required for attaching screws or the like, and the connection is easy and the labor and man-hours required for attachment can be significantly reduced. Also, the electrical wiring work is completed at the same time as the connection to the printed circuit board. Therefore, unlike conventional proximity switches, there is no need to connect the power supply and signal lines with wires, and the influence of noise and induction is reduced, making it possible to improve reliability.
