    Simple Motor Control Circuit

    https://www.google.com/search?q=moto...XwSXgmNqxjUtM:

    This circuit uses (1) N.O. and (1) N.C. auxiliary contact M that are attached to the 3 phase contactor M and operate from the armature.
    The N.O. contact is to the ON light and the N.C. contact is to the OFF light.
