Abstract: Provided are a control switch mechanism, a trigger switch, and an electric tool, having vibration resistance and durability and capable of preventing malfunction. The control switch mechanism (20) includes an optical sensor (21) having a light emitting element (21a) and a light receiving element (21b), and a reflector (22) that increases or decreases an amount of light received by the light receiving element (21b). An increase and a decrease in output of an operation device are controlled along with an increase and decrease in amount of light received by the light receiving element (21b) due to relative movement between the optical sensor (21) and the reflector (22).

Abstract: A trigger switch TS includes a trigger 1 receiving a press through an operation of an operator to be movable to a deepest position in a press direction. The trigger includes: a base shaft member 11, to which a trigger cap 10 is removably attached; and a limiting member 14, supported by the base shaft member to be operable, and able to limit a movement of the trigger. In the trigger where the trigger cap 10 is attached to the base shaft member, if a first press is received, the movement is limited at a limited position not arriving at the deepest position through the limiting member in a limited state. With removal of the received first press, the limiting member transitions to from the limited state to an unlimited state and, if a second press is received following the removal, it is possible to move to the deepest position.

Abstract: A trigger switch which includes a trigger, a shaft member, and a housing includes a fixed engagement portion and a movable engagement portion which is operable that are engaged with each other to inhibit a movement of the trigger. The trigger includes a trigger cap and a holding member that holds the trigger cap and is supported by the shaft member. The trigger cap has a restricting portion and may be attached to and detached from the holding member. When the trigger cap is detached, the movable engagement portion moves to an engagement position, and inhibits the movement of the trigger by a pressing operation. When the trigger cap is attached, the movement of the movable engagement portion is restricted by the restricting portion, and the inhibition of the movement of the trigger is released.

Abstract: A trigger switch includes a trigger that receives a push-in operation of an operator, and a shaft member that supports the trigger. The trigger moves in an operation direction in which the trigger is pushed in by the push-in operation. The trigger includes a trigger cap including a finger hooking part onto which a finger of the operator is hooked, and a holding member that holds the trigger cap and is supported by the shaft member. The trigger cap is attachable and removable to and from the holding member. An electric device includes the trigger switch, and a body device that is driven in response to a push-in operation on the trigger switch. The body device includes a visual check part that allows visual checking of an attachment state of the trigger cap in the trigger switch.
