Abstract:
1. A fastening tool comprising: a housing; a motor assembly in the housing, the motor assembly including an output member and a motor for translating the output member; a contact trip assembly including a contact trip slidably disposed relative to the housing between an advanced position and a retracted position, the contact trip assembly operable to activate a contact trip switch in the retracted position; and a lock-out mechanism including a paddle rotatably fixed relative to the housing between a disengaged position wherein the paddle is located at a position where the contact trip is permitted to slide between the advanced and retracted positions and an engaged position wherein the paddle is located at a position where the contact trip abuts the paddle thereby precluding movement of the contact trip to the advanced position, wherein the paddle further defines a passage having an inner diameter adapted to rotate around a post formed on a backbone fixed to the housing.
