The fastening tool of claim 3, wherein coupling of the cover to the tool body inhibits a state of the mode selector switch from being changed. 6. The fastening tool of claim 3, wherein the cover is formed of a resilient material. 7. The fastening tool of claim 1, wherein positioning of the mode selector switch in the first switch state applies a first predetermined signal to the controller, wherein positioning of the mode selector switch in the second switch state applies a second predetermined signal to the controller, the second predetermined signal being different from the first predetermined signal. 8. The fastening tool of claim 7, wherein the controller defaults to a condition wherein the first operator input must be received prior to the second operator input before the controller activates the power source if the second predetermined signal is not received from the mode selector switch. 9. The fastening tool of claim 7, wherein the first predetermined signal is a signal of a first voltage and wherein the second predetermined signal is a signal of a second voltage. 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. 11. The fastening tool of claim 10, further comprising a cover that is selectively removable from the tool body, wherein coupling of the cover to the tool body covers and obscures the mode selector. 12. The fastening tool of claim 11, wherein the mode selector is an electric switch that generates a switch signal that is responsive to a position into which the mode selector is set. 13. The fastening tool of claim 11, wherein coupling of the cover to the tool body inhibits a state of the mode selector from being changed. 14. The fastening tool of claim 11, wherein the cover is formed of a resilient material. 15. The fastening tool of claim 10, wherein positioning of the mode selector in the first state applies a first predetermined signal to the controller, wherein positioning of the mode selector in the second state applies a second predetermined signal to the controller, the second predetermined signal being different from the first predetermined signal. 16. The fastening tool of claim 15, wherein the controller defaults to a condition wherein the contact trip must 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 if the controller does not receive the second predetermined signal. 17. The fastening tool of claim 15, wherein the first predetermined signal is a signal of a first voltage and wherein the second predetermined signal is a signal of a second voltage. 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. 19. The fastening tool of claim 18, wherein the different mode of operation is a bump feed mode. 20. The fastening tool of claim 18, wherein positioning of the mode selector in the first state causes a first predetermined signal to be applied to the controller, and wherein positioning of the mode selector in the second state causes a second predetermined signal to be applied to the controller, the second predetermined signal being different from the first predetermined signal. 21. The fastening tool of claim 20, wherein the controller defaults to a condition that permits only the sequential feed mode of operation if the controller does not receive the second predetermined signal. 22.
