Abstract
A power tool includes an electric motor, an output member selectively driven by the electric motor and a battery receptacle configured to receive a battery. The power tool also includes a switch trigger moveable between a first position and a second position. The switch trigger inhibits electrical communication between the battery and the electric motor while the switch trigger is in the first position. The switch trigger operates a switch to provide electrical communication between the electric motor and the battery while the switch trigger is in the second position. A lock actuator prevents movement of the switch trigger to the second position while the lock actuator is in a locked position, and the lock actuator permits movement of the switch trigger to the second position while in an unlocked position. The lock actuator is biased into the unlocked position while the battery is positioned in the receptacle.
