摘要： A trigger switch that is 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.

摘要： A trigger switch TS includes a trigger that moves in a pulling direction in response to pressure of a pulling operation and moves in an opposite direction to the pulling direction in response to being released from the pressure. The trigger switch TS includes a lock guide 6 (movable engagement member) that moves in conjunction with movement of the trigger, and a ratchet ring 7 (restraint engagement member) that engages with the lock guide 6 to prevent movement of the lock guide 6 in the opposite direction to the pulling direction. The ratchet ring 7 allows the lock guide 6 to move in the pulling direction, and engages with the lock guide 6 to prevent movement in the opposite direction from a position to which the lock guide 6 is moved in the pulling direction.

摘要： 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.

摘要： Provided is a trigger switch that is incorporated into an electric device such as a power tool and drives a drive part such as a drive motor of the electric device, and is capable of adjusting the force required to press a trigger. A trigger switch TS includes a trigger 1 that moves from a release position in a pulling direction in response to a pulling operation, and a return spring 5 that urges the trigger 1 in a direction opposite to the pulling direction. The return spring 5 included in the trigger switch TS is pressed in the pulling direction by the movement of the trigger 1 and increases the urging force in accordance with the force of pressing. The trigger switch TS includes an adjustment member 6 that adjusts the urging force of the return spring 5 at the release position of the trigger 1.

摘要： A trigger switch includes: a trigger that receives a pushing operation; a shaft member that supports the trigger on one end side thereof; and a housing in which a through hole is opened through which the other end side of the shaft member passes. The shaft member moves inside the housing due to the pushing operation on the trigger. The trigger switch includes a covering member that covers the shaft member in a circumferential direction, has its inside sealed, and is expandable and contractible in an axial direction. The covering member has one end side attached to an outer periphery of the shaft member and has the other end side attached to a periphery of the through hole of the housing.

摘要： A trigger switch includes a trigger, a casing, a compression spring, and a sealing member. The trigger includes a trigger body to which a force is applied when an operator performs a pushing operation, and a trigger shaft extending from the trigger body toward a pushing direction. The casing holds the trigger so as to guide the trigger shaft along the pushing direction when the pushing operation of the trigger is performed. The compression spring is fitted to the outside of the trigger shaft between the trigger and the casing. The sealing member is disposed between the trigger and the casing so as to be fitted to a further outside of the compression spring and cover the trigger shaft and the compression spring.

摘要： 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. The first urging member urges the trigger. 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.
