Abstract
PURPOSE: To enable to test the contact state change with many contact faces to be judged, by applying a magnetic field to a reed switch at varying intensities to space and contact its contacts and comparing the voltage values between the contacts with a predetermined voltage value.
CONSTITUTION: A reed switch 1 is disposed in the position in proximity with a magnet 2 in a housing 3. The one terminal 11 of the reed switch 1 is connected to connection terminals (a), (c) by means of lead wires 4a, 4c and the other terminal 12 to connection terminals (b), (d) by means of lead wires 4b, 4d. The magnetic field spacing and contacting the reed switch 1 is varied with respect to the reed switch 1, whereby its contacts are spaced and contacted, and the voltage between the contacts is measured with a voltmeter 53 and is compared with a predetermined voltage value.
