Lighting Contactors Mechanically Held
Lighting Contactors Mechanically Held use a mechanical latch instead and have a retentive memory. Removal of the voltage from the control circuit allows them to operate quietly and consume a very little amount of control power. They are held in place without the need of a constant power drain. The coil on these types of contactors is far less likely to burn up as it is energized momentarily.
