Abstract
A power tool includes a housing and an electrical power source. A control circuit is electrically connected to the electrical power source and configured to control at least one operation of the power tool. A power tool condition indication circuit is electrically connected to the control circuit comprising a zener diode configured to be conductive at a threshold voltage. The power tool condition indication circuit is configured generate a first indication signal when a voltage controlled by the control circuit exceeds the threshold voltage and generate a second indication signal when a voltage controlled by the control circuit is below the threshold voltage.
