1. A trigger switch, comprising:
a trigger movable in response to a depressing operation;
a movable electrode movable in response to movement of the trigger receiving the depressing operation; and
a fixed electrode located adjacent to a movable range of the movable electrode, the fixed electrode forming a capacitor together with the movable electrode,
wherein a capacitance of the capacitor formed by the movable electrode and the fixed electrode changes as the movable electrode moves according to a depression amount of the trigger enabling the depression amount of the trigger corresponding to the capacitance to be contactlessly detected.
