ABSTRACT:
A trigger assembly and a power tool. The trigger assembly includes a housing and a trigger. The trigger is movably supported by the housing and includes a support portion and a contact portion. The housing includes an opening, and the support portion at least partially extends into the opening. In some aspects and in some constructions, the support portion has a first width, and the contact portion has a second width, the second width of the contact portion being greater than the first width of the support portion. The trigger includes an upper protrusion that may prevent the operator's finger from being pinched between the trigger and the housing. The trigger may include an angled portion extending between the support portion and the contact portion on opposite sides of the trigger. The angled portion may include multiple ribs defining grooves between the ribs.
