Abstract
A fastener-driving tool includes a housing, a workpiece-contacting element movable between a rest position and an activated position, and a trigger movable between a rest position and an activated position. The tool includes an actuation lever movably connected to the trigger and a control valve including an actuating pin and an electromagnet where the actuating pin is movable between a rest position and an activated position. In a powered mode, the electromagnet is energized and attracts the actuation lever to the actuating pin and hold the actuation lever and the actuating pin in respective activated positions such that the tool is actuated each time the workpiece-contacting element contacts a workpiece. In a non-powered mode, the electromagnet is not energized such that the tool is actuated each time the workpiece-contacting element and the trigger are each moved from the rest position to the activated position in a designated sequence.
