Abstract: The present invention relates to a keyboard switch including a base, a supporting member, a spring, a button and an upper cover. The supporting member includes a first plate connected to the base to seal the opening, a tube extending substantially perpendicularly from a surface of the first plate, and a plurality of blocks extending substantially perpendicularly from the first plate and configured around the tube. There is a gap between the tube and the plurality of blocks. The base and the supporting member may be made of different materials and colors from the base, so that the supporting member may have a good light-shielding performance and durability; and the base may be made of a collocation of different materials and colors, and has a wide design space.

Abstract: Multi-point parallel synchronous drive device, which includes a drive mechanism and several stages of driven mechanisms drivingly connected. The drive mechanism comprises a first power output for rotatably connecting with a power output shaft, and a second power output disposed below the first power output and parallel to the first power output along a power output direction. The several stages of the driven mechanism are arranged at intervals in the power output direction. The second power output of the drive mechanism is drivingly connected with a power input of the adjacent driven mechanism along the power output direction, and the adjacent two-stage driven mechanisms are drivingly connected along the power output direction. The driven mechanism at any stage comprises a power output for rotatably connecting with the power output shaft. The device can be applied to the a solar tracking system, with the main shaft as the power output shaft.

Abstract: A keyboard switch comprises an upper cover (1), a base (2), a fixed terminal (3), a movable terminal (4) and a pressing component (5). A guide column (21) is disposed on the base, the pressing component is installed on the guide column on which a return spring (8) is fitted, the upper end of the pressing component is exposed out of the upper cover for pressing, and the upper cover is fastened to the base to form a cavity, the fixed terminal and the movable terminal are disposed on one side of the pressing component in the cavity, and one end of the fixed terminal and one end of the movable terminal penetrate out of the base to be connected to an external circuit. The pressing component moves up and down to drive the movable terminal to move, and further to control contact and disconnection between the other end of the movable terminal and the other end of the fixed terminal.

Abstract: A thin switch includes a pressing cup (1), a base (2) and a top cover (3). A conductive component (4), a spring (5), a fixed terminal (6) and an elastic wire (7) are disposed in a space defined by buckling the base and the top cover. The elastic wire is arranged below the conductive component, one end of the elastic wire is fixed on the base and the other end is disposed under a boss of the pressing cup. When the pressing cup is pressed down, the conductive component is driven to contact the fixed terminal to turn on the switch, and the elastic wire is driven to descend at the same time. When the pressing cup is pressed down to a preset position, the elastic wire separates from the pressing cup, and bounces back upwards to strike the dome to make a sound.
