A wiring diagram is a simplified standard pictorial representation of an electrical circuit. Most lighting and heating applications require a contactor to control the loads. Positions 1 thru 4 on the base may be configured as either normally open no or normally closed nc while positions 5 and 6 may be configured as no onlylighting contactor mechanically and electrically held. It also ensures the removal of coil from the circuit for noise free operation and the elimination of all coil losses. The mechanically held operation ensures that the contactor will not switch to off during control power failure. Unlike a magnetic starter however a lighting and heating contactor is designed for lighting and resistive.
These contactors do not change state and disconnect power from the load during a loss of control power whether momentary or sustained.
