Patent number: 9316352Abstract: An electrical tool includes a trigger lock assembly having a trigger lock member, a detent assembly, and a return spring. The trigger lock member is movable relative to a trigger between a neutral position, in which the trigger is movable between an off position and an on position, a lock-off position, in which the trigger is prevented from moving from the off position, and a lock-on position, in which the trigger is maintained in the on position. The detent assembly is operable to releaseably retain the trigger lock member in each position and includes a recess associated with each position. The detent assembly also includes a projection selectively engageable in one of the recesses to releasably retain the trigger lock member in the associated position, and a biasing member biasing the projection into engagement. The return spring is operable to bias the trigger lock member toward the neutral position.Type: GrantFiled: June 18, 2014Date of Patent: April 19, 2016Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Troy C. Thorson, Scott D. Eisenhardt, Terry L. Timmons
