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 capable of suppressing wear of a sliding electrode part and a device including the trigger switch are provided. A trigger switch includes a front sub-brush and a rear sub-brush that, when a drive part is driven by a movement of a trigger caused by a push-in operation to the trigger, move from an on-position where they contact a front sub-electrode and a rear sub-electrode on a substrate to an off-position where they do not contact the front sub-electrode and the rear sub-electrode. As the front sub-brush and the rear sub-brush move from the on-position to the off-position, a contact between the front sub-brush and the rear sub-brush and the substrate are 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.

Abstract: 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.

Abstract: 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.

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.

Abstract: A switch may include: a movable member comprising a movable piece extending from a swing shaft and being swingable around the swing shaft; and a pressing member configured to press the movable piece while moving in response to a pushing operation, the movable piece swinging in response to pressing from the pressing member. The pressing member comprises a first contact portion configured to slide along an extending direction of the movable piece in a state of being in contact with the movable piece due to movement by the pushing operation, and a second contact portion configured to be in contact with the movable piece at a position different from a position where the first contact portion is in contact, due to the movement by the pushing operation, and the pressing member presses the movable piece by the first contact portion and the second contact portion in a contact state.

Abstract: A contact substrate is moved to cause a connection terminal and a connection terminal to slide on the contact substrate to change the contact state of the connection terminal and the connection terminal to a first slide contact and to a second slide contact. This switches the electrical connection/disconnection between the connection terminal and the connection terminal.
