A trigger device includes a circuit board, an arched sheet, and a noise-reducing unit that includes first and second electroconductive sheets respectively connected to first and second nodes of the circuit board. The arched sheet is mounted to the second electroconductive sheet and is pressible from a preset state to a bent state, with the arched sheet being deformed and proximate to the first electroconductive sheet, and further from the bent state to a contact state, with the second electroconductive sheet being compressed and with a central portion of the arched sheet being brought into contact with the first electroconductive sheet to thus electrically connect the first and second nodes.

Disclosed is a rotary bridge micro-switch. The rotary bridge micro-switch comprises an insulating base, wherein a first terminal, a second terminal and a third terminal are arranged on the insulating base and are spaced from one another by the insulating base; and the insulating base is rotatably connected to a conducting plate having one end abutting against the first terminal. The rotary bridge micro-switch further comprises a spring having two ends respectively connected to the other end of the conducting plate and the insulating base. When the spring is not compressed, the first terminal is connected to the second terminal through the other end of the conducting plate. When the spring is compressed, the first terminal is connected to the third terminal. The rotary bridge micro-switch can be pressed to realize switching between two circuits.

A control device for a bicycle is disposed on a handlebar and includes a body, an electronic module, at least one switch, and at least one input member. The body includes a plugged portion and a holding portion. The plugged portion is disposed inside the handlebar via an opening of the handlebar. The holding portion is connected to the plugged portion and is disposed outside the opening. The electronic module is disposed in the plugged portion and has at least one surface. The switch is disposed on the surface of the electronic module to selectively control the electronic module to send an electronic signal. The input member is disposed on the holding portion and extends into the plugged portion and moves in an operating direction to actuate the switch. The operating direction is not perpendicular to the surface and a longitudinal axis direction of the plugged portion.

The disclosure provides a key module including a bottom plate, a keycap and a scissor structure. The keycap is located above the bottom plate. The key cap includes a pivoting member protruding from the bottom surface and a sliding member. The pivoting member has a pivot hole and a hollowed-out area communicating with the pivot hole. The scissor structure is disposed between the bottom plate and the keycap, and includes a first leg and a second leg pivotally connected to each other, the first side of the first leg and the second side of the second leg are connected to the bottom plate, the third side of the first leg is rotatably connected to the pivoting member of the keycap, and the fourth side of the second leg is slidably connected to the sliding member of the keycap.

A key switch includes a base, a key cap, a first support member and a second support member. The key cap is disposed with respect to the base. The first support member and the second support member are disposed between the key cap and the base. The first support member has a first linkage structure. The second support member has a second linkage structure. The first linkage structure and the second linkage structure abut against each other, such that the first support member and the second support member rotate synchronously with respect to a horizontal axis. When one of the first support member and the second support member horizontally moves with respect to the other one of the first support member and the second support member within a predetermined range along the horizontal axis, the first linkage structure and the second linkage structure keep abutting against each other.

A pressure button for a touch-sensitive surface, a physical interface for a touch-sensitive surface, and a protection element for a touch-sensitive surface, in particular a touch screen of a terminal such as a smart phone or a tablet. The pressure button has a contact switch passing through the pressure button, from the upper surface to the lower surface of said pressure button. The contact switch is suitable for allowing interaction with a terminal via a touch-sensitive surface when the pressure button is positioned on the latter. The user can thus interact with the terminal by using a pressure button without requiring connectors for this interface.

The disclosure provides a positioning member includes a bottom plate and a shielding layer. The bottom plate includes a body part and a protruding part. The body part has a connection part. The protruding part has a through hole. The body part is upwardly connected to the protruding part through the connection part, such that the body part, the connection part and the protruding part jointly enclose an accommodating space below the through hole. An joint member having a stud and a head connected to the stud, wherein the stud passes through the through hole to be fixed in the accommodating space via the head. The shielding layer is disposed on the body part, partly extending to the through hole of the protruding part to shield the protruding part exposed by the joint member. A keyboard is further provided.
