A trigger switch according to one or more embodiments may include a pressure sensor such as a pressure sensitive element that detects a depressed amount of a trigger in response to a depressing operation on the trigger. A trigger switch may include a trigger movable in response to a depressing operation, an urging member including a first end in contact with the trigger and a second end and urging the trigger in a direction opposite to a depressing direction in which the trigger is depressed, an elastic member in contact with the second end of the urging member, and a pressure sensor in contact with the elastic member to detect pressure applied from the elastic member.

Trigger switch

A trigger switch used in electric devices such as various types of electric tools may be provided that drives a drive unit, such as a drive motor of the electric device, by pushing a trigger. A trigger switch includes a mode switching lever that switches between a constant speed mode in which the drive unit is driven at constant speed and a shift mode in which the drive unit is driven by an output corresponding to a pushing amount of a trigger. Further, the mode switching lever includes a regulating portion that regulates the pushing amount of the trigger according to the switched mode.

A switch according to one or more embodiments may include a movable unit movable in response to an operation. A drive unit is drivable in response to movement of the movable unit. The switch may include an operation-linked unit movable in response to the movement of the movable unit and an operation follower unit spaced from the operation-linked unit to move in response to movement of the operation-linked unit with a magnetic force between the operation follower unit and the operation-linked unit. At least one of the operation-linked unit or the operation follower unit is magnetic. The drive unit is drivable in response to movement of the operation follower unit. The operation follower unit accommodated in a chamber is spaced from the operation-linked unit.

Switch

A trigger switch according to one or more embodiments may include a first conductive plate (movable electrode) movable in response to movement of a trigger receiving a depressing operation, and a second fixed electrode (fixed electrode) located adjacent to a movable range of the first conductive plate with a space in between. The second fixed electrode forms a capacitor together with the first conductive plate. The capacitor formed by the first conductive plate and the second fixed electrode has a capacitance that changes as the first conductive plate moves.

A trigger switch may include a first urging member urging a trigger, a shaft including a first end attached to the trigger, a first movable member connected to a second end of the shaft, a second movable member, a second urging member located between the first movable member and the second movable member, and a contact portion to be in contact with the second movable member moved in a depressing direction. In response to a depressing operation on the trigger, the first movable member, the second movable member, and the second urging member move in the depressing direction until the second movable member comes in contact with the contact portion. In response to an additional depressing operation on the trigger with the second movable member in contact with the contact portion, the first movable member moves in the depressing direction, and the second urging member urges the first movable member.
