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.

1. A fastener-driving tool including a trigger control mechanism, said tool comprising: a housing;a workpiece-contacting element movably connected to said housing, said workpiece-contacting element being movable between a rest position and an activated position;a trigger movably connected to said housing, said trigger being movable between a rest position and an activated position;an actuation lever movably connected to said trigger; anda control valve including an actuating pin and an electromagnet, said actuating pin being movable between a rest position and an activated position;wherein in a powered mode, said electromagnet is energized causing said actuation lever to be attracted to said actuating pin and hold said actuation lever and said actuating pin in said respective activated positions such that the tool is actuated each time said workpiece-contacting element contacts a workpiece and moves to said activated position; andwherein in a non-powered mode, said electromagnet is not energized such that the tool is actuated each time said workpiece-contacting element and said trigger are each moved from said rest position to said activated position in a designated sequence. 2. The tool of claim 1, wherein said actuation lever includes a swivel member for maintaining contact between said actuation lever and said actuating pin when said trigger is moved to said activated position. 3. The tool of claim 1, wherein said actuating pin includes a swivel member for maintaining contact between said actuation lever and said actuating pin. 4. The tool of claim 1, wherein said actuation lever is movable between a first position, wherein said actuation lever is spaced from said actuating pin, and a second position, wherein said actuation lever is in contact with said actuating pin. 5. The tool of claim 4, wherein said actuation lever includes a bias member configured to bias said actuation lever to said first position. 6. The tool of claim 1, wherein said actuating pin includes a bias member configured to bias said actuating pin toward said rest position. 7. A fastener-driving tool including a trigger control mechanism, said tool comprising: a housing;a workpiece-contacting element movably connected to said housing and including a first position sensor assembly, said workpiece-contacting element being movable between a rest position and an activated position;a trigger movably connected to said housing and including a second position sensor assembly, said trigger being movable between a rest position and an activated position;an actuation lever movably connected to said trigger; anda control valve including an actuating pin and an electromagnet, said actuating pin being movable between a rest position and an activated position;wherein in a powered mode, when said first position sensor assembly senses that said workpiece-contacting element is in the activated position and said second position sensor assembly senses that said trigger is in the activated position, said electromagnet is energized causing said actuation lever to be attracted to said actuating pin and hold said actuating pin in said activated position such that the tool is actuated each time said workpiece-contacting element contacts a workpiece; andwherein in a non-powered mode, said electromagnet is not energized such that the tool is actuated each time said workpiece-contacting element and said trigger are each moved from said rest position to said activated position in a designated sequence. 8. The tool of claim 7, wherein said actuation lever includes a swivel member for maintaining contact between said actuation lever and said actuating pin. 9. The tool of claim 7, wherein said actuating pin includes a swivel member for maintaining contact between said actuation lever and said actuating pin. 10. The tool of claim 7, wherein said actuation lever includes a bias member configured to bias said actuation lever to said first position. 11. The tool of claim 7, wherein said actuating pin includes a bias member configured to bias said actuating pin toward said rest position. 12. The tool of claim 7, wherein said first position sensor assembly includes a first sensor associated with one of said housing and said workpiece-contacting element and a first signal generator associated with the other of said housing and said workpiece-contacting element, and said second position sensor assembly includes a second sensor associated with one of said housing and said trigger and a second signal generator associated with the other of said housing and said trigger, wherein said first sensor senses a signal generated by said first signal generator when said workpiece-contacting element is in said activated position and said second sensor senses a signal generated by said second signal generator when said trigger is in said activated position.
