1. A fastening tool for installing fasteners into a workpiece, the fastening tool comprising:
- a contact trip switch that is actuated in response to a first operator input;
a trigger switch that is actuated in response to a second operator input;
a driver that is movable along an axis;
a motor assembly having a flywheel that is driven by a motor and an actuator that can be actuated to drive the driver into engagement with the flywheel to cause the driver to move along the axis;
a controller that is configured to selectively activate the motor assembly to cause the driver to translate along the axis at least partially in response to actuation of the contact trip switch and the trigger switch, the controller including a mode selector switch having a first switch state and a second switch state, wherein placement of the mode selector switch into the first switch state requires that the contact trip switch be actuated prior to actuation of the trigger switch before the controller actuates the actuator, and wherein placement of the mode selector switch into the second switch state permits the controller to activate the actuator when both the contract trip switch and the trigger switch have been activated regardless of an order in which the contract trip switch and the trigger switch have been activated.

Abstract
A fastening tool having a contact trip switch, a trigger switch, a driver, a motor assembly and a controller. The controller is configured to selectively operate the motor assembly in response to inputs received from the contact trip switch and the trigger switch. The controller includes a mode selector switch having a first switch setting, which can permit bump-feed operation of the fastening tool, and a second switch setting, which prohibits bump-feed operation of the fastening tool.

10. A fastening tool for installing fasteners into a workpiece, the fastening tool comprising:
-
a nosepiece; a contact trip that is coupled to the nosepiece and movable between a first contact trip position and a second contact trip position, the contact trip being biased into the first contact trip position and moving into the second contact trip position in response to a first operator input; a tool body that is coupled to the nosepiece; a driver that is housed in the tool body and movable along an axis through at least a portion of the nosepiece; a motor assembly for translating the driver along the axis; a trigger that is coupled to the tool body, the trigger being movable between a first trigger position and a second trigger position, the trigger being biased into the first trigger position and moving into the second trigger position in response to a second operator input; a controller that is configured to selectively activate the motor assembly, the controller including a mode selector having a first state and a second state, wherein placement of the mode selector into the first state requires that the contact trip be moved into the second contact trip position prior to movement of the trigger into the second trigger position to actuate the motor assembly and cause the driver to translate along the axis, and wherein placement of the mode selector into the second state permits the controller to activate the motor assembly and cause the driver to translate along the axis regardless of an order in which the contact trip is moved into the second contact trip position and the trigger is moved into the second trigger position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A fastening tool for installing fasteners into a workpiece, the fastening tool comprising:
-
a tool body; a contact trip that is coupled to the tool body and movable between a first contact trip position and a second contact trip position, the contact trip being biased into the first contact trip position and moving into the second contact trip position in response to a first operator input; a driver that is housed in the tool body and movable along an axis; a motor assembly for translating the driver along the axis, the motor assembly including a flywheel and an actuator, the driver being disposed between the flywheel and the actuator; a trigger that is coupled to the tool body, the trigger being movable between a first trigger position and a second trigger position, the trigger being biased into the first trigger position and moving into the second trigger position in response to a second operator input; a controller that is configured to selectively move the actuator to pinch the driver between an actuator member and the flywheel, the controller including a mode selector having a first state and a second state, wherein placement of the mode selector into the first state mandates sequential mode operation of the fastening tool and wherein placement of the mode selector into the second state permits the fastening tool to be operated in a different mode of operation. - View Dependent Claims (19, 20, 21, 22)

23. A fastening tool comprising:
-
a tool body; a driver mounted on the tool body and movable along an axis; a motor assembly that is configured to drive the driver along the axis; a contact trip that is coupled to the tool body and movable between a first contact trip state and a second contact trip state, the contact trip being biased into the first contact trip state and moveable into the second contact trip state in response to a first operator input; a trigger that is coupled to the tool body and moveable between a first trigger state and a second trigger state, the trigger being biased into the first trigger state and moveable into the second trigger state in response to a second operator input; an electronic controller coupled to the motor assembly and operable for actuating the motor assembly so as to move the driver along the axis, the electronic controller being operable in a first mode, which actuates the motor assembly only if the contact trip is moved into the second contact trip state prior to movement of the trigger into the second trigger state, and a second mode, which permits the motor assembly to be actuated when the trigger is moved into the second trigger state prior to movement of the contact trip into the second contact trip state. - View Dependent Claims (24, 25, 26)

27. A method comprising:
-
providing an electric fastening tool having a contact trip, a trigger, a driver that is moveable along an axis, and a mode selector switch, the mode selector switch having a sequential setting and a bump-feed setting; placing the mode selector switch into the bump-feed setting; and operating the tool such that; a) one of the trigger and the contact trip is moved into an actuated state; b) the other one of the trigger and the contact trip is moved into an actuated state; c) the driver is translated along the axis; d) the contact trip is moved into an unactuated state while the trigger is maintained in the actuated state; e) the contact trip is moved back into the actuated state while the trigger has been maintained in the actuated state; and f) the driver is translated along the axis without first changing the trigger to an unactuated state.
