ABSTRACT:
A method for manufacturing a position detector having a movable permanent magnet (5) and a circuit board (6) having a magnetic sensor circuit (10.about.13) mounted thereon for detecting the displacement of the permanent magnet. A selective connection portion (8,9) in the magnetic sensor circuit capable of being selectively placed into at least two different circuit patterns exhibiting two different output characteristics (A,B) is provided. Then, the connection in the selective connection portion (8,9) is changed by adding an electrical conductor (FIGS. 1a, 1b) or removing (FIGS. 2a, 2b) portions of pattern conductors in the selective connection portion (8,9) to place the magnetic sensor circuit into either one of the at least two different circuit patterns (FIGS. 4,5) according to necessity.
