AC contactor N/O 25A

AC contactor N/O 25A

In a normally open switch, when the switch is off the contacts are open. This means the electrical connection is broken so the switch is “off”. In Normally Closed switches, the contacts are closed which connects the switch meaning that when they are not compressed they are switched “on”

AC contactor N/O 25A

De-energized state: When the contactor’s coil has no voltage, the N/O contacts are open.

Energized state: When the coil receives a voltage signal (e.g., from a thermostat). It creates a magnetic field that pulls the contacts together, closing the N/O contacts.

Simultaneous action: When the N/O contacts close. The contactor’s main contacts also close, allowing high current to flow to the AC unit’s components
