ABSTRACT:
Disclosed a trigger switch having a trigger to be locked stably when it is pulled in. The trigger has wall surfaces disposed oppositely leaving a space therebetween. Pivotal holes are formed in the wall surfaces and a pivotal shaft is inserted in said holes. Rotary shaft holes are formed in the wall surfaces, and a rotary shaft for inverting a switch is inserted in the rotary shaft holes. A stopper for stopping the trigger from being pulled while rotating about the pivotal shaft is mounted between the pivotal shaft and the rotary shaft. The stopper includes a stopper shaft engaged in stopper holes formed in the wall surfaces. A stopper button is mounted at an end of the stopper shaft. When the stopper button is pushed, the stopper shaft is moved to place a thinned portion thereof into the stopper holes, thus releasing the trigger from the stopper.
