A switch device includes a knob, a support to support the knob to be movable in a linear direction, a switch main body to make electrical switching upon an operation of the knob, and a detent member to give a detent feeling to the operation on the knob. The knob, the switch main body and the detent member are serially arranged in the linear direction.

A push switch includes an operating part configured to be pressed in a first direction, an elastic holding member configured to hold the operating part such that the operating part can vibrate in a second direction orthogonal to the first direction, a frame member configured to hold the elastic holding member such that the elastic holding member can vibrate in the second direction, and a vibrator configured to generate a vibration in the second direction, the vibrator being provided in the elastic holding member.

A switch assembly including a socket, a top cap, and an intermediate cart located in the socket. The intermediate cart is slidable with the socket. The top cap is in a spherical or pivot engagement with the intermediate cart. An activation force of the sliding movement is lower than an activation force of the spherical or pivot movement.

A push switch contains a circuit substrate, two fixed contacts disposed on the circuit substrate, a dome-shaped spring which is disposed above the two fixed contacts and can be displaced between a first position in which the two fixed contacts are in a non-conductive state and a second position in which the two fixed contacts are in a conductive state and a conductive elastic member disposed on a surface of the dome-shaped spring facing the circuit substrate and having a surface facing the two fixed contacts. At least the surface of the conductive elastic member facing the two fixed contacts has conductivity. When the dome-shaped spring is displaced to the second position, the two fixed contacts are in the conductive state through the conductive elastic member.

A keyswitch includes a bottom board, a cap structure, a lifting mechanism, and an elastic member. The lifting mechanism is detachably connected to the cap structure and the bottom board to make the cap structure movable upward and downward relative to the bottom board. The elastic member is connected to the cap structure so as to be detached from the lifting mechanism together with the cap structure when the cap structure is separate from the lifting mechanism.

A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.

The shell is provided with an axial opening at the top and a guide track structure inside. The movable terminal is provided inside the shell and forms an arm spring. The actuating lever is threaded through the axial opening, with a flat slope on one side and a positioning slope on the other. The actuating lever is provided with a guiding structure, and the positioning slope is provided with a positioning structure. Moving upwards along the circumference, the actuating lever has a position 1 and a position 2. When the actuating lever is at position 1 or position 2, the guiding structure joins the guide track structure. When the actuating lever is at position 1, the arm spring comes into contact with the flat slope and slips. When the actuating lever is at position 2, the arm spring comes into contact with the positioning slope and slips.

A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes a movable block, a push block and a stopper. While the movable block is pushed and moved in response to a pushing force, the push block is correspondingly moved. While the push block is moved, the stopper is pushed by the push block, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.
