Lighting Contactor Wiring Diagram. Many large pieces of equipment are powered directly from high voltage lines. It goes in series with contactor power and a normally open contact on the contactor.
A lighting contactor switch operates at a lower but. Wiring diagrams help technicians to see how the controls are wired to the system. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
Lighting contactors are relay switches that control the flow of electricity through a circuit powering the lighting in a given area.
Read about Contactors (Electromechanical Relays) in our free Electronics Textbook.
Pilot lights may be connected in parallel with the forward and reverse contactor coils, indicating which contactor is energized and thus which direction the motor is running. I have prepared a wiring diagram. Electronic ballast has six ports, two ports out of six ports are for the input, and the remaining four ports are for output.
