Abstract: A portable electric tool has an ON-OFF trigger operated switch and a locking member to hold the trigger with the switch in ON position. The trigger has one end pivoted in the handle of the tool. A portion of the trigger extends outwardly from an opening in the handle so that it can be manually moved inwardly to ON position by the operator while holding the tool by its handle. Such inward movement is resiliently resisted and the ON position is momentary so that when the operator releases actuating pressure, the trigger automatically moves to switch OFF position.
