Power to Lock
With a Power to Lock switch, connect pin 3 (green wire) to 24V DC to lock
the switch (for example, extend the locking bolt). When you disconnect pin 3,
it unlocks the switch.
If power is removed from a Power to Lock switch in the locked position, the
switch unlocks.
In either type of lock, the locking bolt never extends in the absence of the
actuator.
