Normal operation is that there is continuity
between connector terminals 2 and 3
when the plastic magnet is getting close to
the proximity switch and there is no
continuity between connector terminals 2
and 3 when the plastic magnetic is getting
away from the proximity switch.

Caution
Do not short-circuit the battery.
Follow the steps below to connect the
battery and a voltmeter to the connector
terminal of the proximity switch NO (+).
Connect the battery (+) to the connector
terminal (+), and the battery (-) to the
connector terminal (-).
Connect the voltmeter (+) to the
connector terminal Vout (+), and the
voltmeter (-) to the connector terminal
(-).
It is normal that the voltage between
connector terminals 2 and 3 is the battery
voltage (12 V) when the plastic magnet
gets close to the proximity switch, and that
voltage drops to (0 V) when the plastic
magnet is away from the proximity switch.
