Abstract
An electric tool is provided with a second switch that is actuated in order for the tool to be used. The second switch is on a second handle that is grasped by the operator with a different hand than the hand that actuates the main trigger switch. Communication between the second switch and the tool occurs with a wireless signal indicating that the second switch has been actuated.
