摘要:
To provide a trigger switch having a simple structure that is capable of reducing bouncing when the contacts are switched ON/OFF, the trigger switch includes a switch mechanism integrated in a single assembly a power control unit that turns a plurality of switches provided on the switch mechanism ON/OFF depending on a degree of retraction of the control unit by moving a pressing member over a top of a seesaw-shaped switching bar, a motor brake and control element short-circuit unit that drives a movable armature having two short-circuit contacts and is sandwiched and held between two springs, and a speed control unit that slides a plurality of moving contacts disposed in parallel over sliding contacts disposed on a sliding circuit substrate so as to control both the supply of power and a control element, and thus control the rotation speed of a motor.
