Abstract
A power tool is provided which includes a motor assembly having a rotatable motor shaft mechanism, and a motor control coupled to the motor assembly and operable between a normal off condition de-energizing the motor and an on condition energizing the motor. The tool includes a rotatable tool shaft mechanism, and a clutch shiftable between a normal disengaged condition decoupling the motor shaft mechanism from the tool shaft mechanism and an engaged condition coupling the motor shaft mechanism to the tool shaft mechanism. A trigger member is engageable with both the motor control and the clutch and is moveable between a first position, wherein the motor control is in its off condition and the clutch is in its disengaged condition, and a second position holding the motor control in its on condition and the clutch in its engaged condition for driving the tool shaft mechanism. The trigger member is designed to prevent premature energization of the motor assembly.
