たことを特徴とするトリガスイッチ。(1) A trigger operating member is held in the switch case so that it can be pushed in against the return spring force, and as the pushing stroke of the operating member increases, the output is increased sequentially, and the pushing stroke is increased. In the trigger switch having a variably controlled adjuster, a stroke adjuster rotatably supported by the operating member in an immovable manner has a plurality of steps formed at the inner end thereof, and the operating member has a plurality of steps. A stopper is provided protruding from the switch case and comes into contact with the stepped portion of the adjuster at a predetermined push-in position, and the adjuster is rotated around the shaft portion so that each stepped portion of the adjuster is pressed against the stopper. A trigger switch characterized by being configured to change a contact position.
