Claims

[Scope of utility model registration request]

A trigger-type switch that moves an actuating plate by a certain stroke by rotation of a trigger attached to a case, and turns on and off a switch in the case with the actuating plate, and the switch includes a small diameter portion in the axial direction, a lock pin that has a continuous medium diameter part and a large diameter part and is attached to the case so as to slide through both sides of the trigger; and a lock pin that is fixed to a side surface of the trigger and that the lock pin passes through. a first lock plate having a cam hole formed in series with a wide hole that accepts the medium diameter portion and the small diameter portion of the lock pin and a narrow hole that accepts only the small diameter portion; , an engagement that is fixed to the side surface of the trigger in correspondence with the first lock plate, and that allows the lock pin to pass through the large diameter portion and the medium diameter portion at a position corresponding to the narrow hole of the cam hole. a second lock plate having a mating hole, a first biasing means that constantly biases the lock pin in a predetermined direction, and a wide hole of the cam hole that moves the trigger to a position corresponding to the lock pin. and a second biasing means that constantly biases the rotation, and the lock pin is pushed against the biasing force of the first biasing means so that the middle diameter portion is located in the cam hole. from an off-lock position where the small diameter portion prevents rotation of the trigger to an off-lock release position where the small diameter portion is positioned to allow rotation of the trigger; and an off lock release position where the large diameter portion passes through the engagement hole of the second lock plate. and can be engaged with the peripheral edge of the engagement hole to move the trigger to an on-lock position that continuously prevents the trigger from returning to rotation, and selectively release the engagement of the large diameter portion with respect to the engagement hole. A switch characterized by the following.
