A power tool is provided including an electric motor, a power terminal receiving electric power form a power supply, an actuator, a power switch circuit disposed between the power terminal and the electric motor, and a controller controlling a switching operation of the power switch circuit. A power contact switch is coupled to the actuator and disposed on a first current path to selectively connect the power switch circuit to the power supply. A solid-state load switch disposed on a second current path from the power terminal to the controller is controllable via output of the power contact switch or a self-activating feedback signal from the controller. A solid-state override switch is provided controllable via a self-deactivating feedback signal from the controller and having an output commonly coupled to the output of the power contact switch to turn off the load switch even when the power contact switch is closed.
