Fastener-driving tool including a reversion trigger

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;
• and
• a 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;
• and
• wherein 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.

• 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;
• and
• wherein 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.
