ABSTRACT:
A fastener driving device includes a trigger assembly operatively disposed between a contact trip assembly and an actuating assembly. The trigger assembly includes a trigger member, an actuating member, and an automatic mode selecting mechanism. The mode selecting mechanism includes a mode selecting member having a connection with the actuating member to make the mode selecting member (1) move with the actuating member between first and second positions of the actuating member, and (2) have relative movement with respect to the actuating member so that the mode selecting mechanism (a) retains the actuating member in the first position in response to an initial movement of the trigger member to the operative position, and (b) retains the actuating member in the second position in response to an initial movement of the contact trip assembly into the operative position and a subsequent movement of the trigger member into the operative position.
