Selected User Reviews For NTE Electronics 54-630 Magnetic Alarm Reed Switch, SPST-NO Circuit, NO for Closed Loop System Action, Magnet Actuator, White
Despite its small size and poor quality, this switch is an impressive device. There are approximately one inch of length and they are quite inconspicuous in appearance. This item includes screws and adhesive mounting. This is described by the manufacturer as Normally Open (NO), which normally means that it is open when the contacts are apart. Some manufacturers call this NC, so remember to read the manufacturer's description
In other words, when the contacts are close together, the circuit is closed, and when the contacts are apart, the circuit is open.
Worked like a charm.
Exactly what you're looking for.
The model trains I have are equipped with this magnetic position sensor. I have tested it thoroughly, and it worked flawlessly.
An open switch would not normally be found here! In the closed state, the contacts are in contact with each other.
