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.
