Abstract:
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.
