Abstract

The object of the present invention is to provide a cheap small detection switch which is capable of accurate detection and has degrees of freedom in arrangement of a printed circuit board. The detection switch comprises a case (1) made of an insulating material and having housing parts (1c, 1d); a printed circuit board (6) installed to the case (1) in a state to be housed in the housing part (1c), and a magnetic transducer (5) connected to a conductive pattern (7) provided on this printed circuit board (6). In the switch, the magnetic transducer (5) is housed in the housing part (1c) and installed to the case (1) in a state to be positioned to the case (1). When the magnetic transducer (5) is installed to the case (1) in such a state to be positioned to the case (1), the installation error of the magnetic transducer (5) becomes much smaller, the installed position of the magnetic transducer (5) becomes more accurate in comparison with conventional ones, and the accurate detection can be expected in the detection switch thus provided.
