Low voltage is supplied by batteries, or by a transformer that converts line voltage to a low voltage. Low voltage (when the source is operating properly) will not provide a shock from contact. However, a high current, low voltage short circuit (automobile battery) can cause an arc flash and possible burns. Ohms Law and Low Voltage


When the START button is released, the circuit will remain complete, because the M a contact remains closed, shunting the open start switch. When a low voltage condition occurs, the M coil will drop out at some pre-determined value of voltage, and the M and M a contacts will open. The START button must then be pushed to restart the motor.
