Abstract: A mechanical timer mechanism can include a driven gear mounted to a rotary damper and a drive gear operably coupled to the driven gear. In bump mode, movement of an auxiliary trigger to its actuating position can initially move the drive gear from a home position into its wind-up position. Thereafter, a contact trip can continue to move the drive gear to its wind-up position and an actuator of a principal trigger to its actuating position each time the contact trip is actuated, unless the timing mechanism has timed-out between actuations. In sequential mode, the drive gear can be moved into a timer lock-out position which holds the contact trip in a bypass position in which the contact trip will not engage the actuator of the auxiliary trigger unless the auxiliary trigger is moved to its actuating position before actuation of the contact trip.
