<p>A new and improved trigger control assembly (110) for switching the mode operation of the fastener-driving tool (112) between a sequential mode of operation and a bump firing mode operation. The trigger member (134) is provided with a pair of throughbores (140, 142) for alternating accommodating a pivot pin (144) by which the trigger member (134) may be pivotally mounted upon the fastener-driving tool housing (114) at two different positions whereby the workpiece contacting element (116) of the fastener driving tool (112) will engage the actuation lever (160) of the trigger member (134) at different positions so as to achieve the sequential and bump-firing modes of operation.</p> |
