Abstract
A trigger switch for hand-held electric power tools in which an actuating arm for actuating a switch mechanism is pivotally supported in a case by way of a pivot shaft pivotally supported by a pair of parallel lateral walls defining the case, and a trigger member having a front end and a pair of lateral flanges is pivotally supported by the case in a coaxial relationship with the pivot shaft by way of the lateral flanges. By securely coupling an extension of the pivot shaft with one of the flanges, the switch mechanism internally accommodated in the case can be actuated by operating the trigger member. Since the switch mechanism is internally accommodated in the case, a considerable saving of space can be accomplished. Since the coupling between the pivot shaft and the trigger member can be accomplished by the extension of the pivot shaft passed through the case by way of a round opening provided in the case, sealing of the switch mechanism can be easily accomplished.
