A safety waterproof invisible switch and a sanitary ware are provided. The safety waterproof invisible switch comprises a button switch, a first member, a second member, a first magnet, and a second magnet. The first magnet is disposed on a button of the button switch, and the second magnet is disposed on the second member. The first member has a hollow cavity. The button switch disposed with the first magnet is disposed in the first member. While the second magnet is adjacent to or in contact with the first member and when magnetic poles of a same polarity of the first magnet and the second magnet oppose each other, the button of the button switch is moved in a pressed direction of the button by a repulsive force.

A hand-held rotary power tool includes a housing that provides a manual grip zone that is grasped by the user during operation of the tool. The housing includes a switch opening that overlies an electrical switch that controls operation of a tool motor. The tool includes a switch actuator that is disposed in tool housing so as to be accessible to a user of the tool via the switch opening and is operable to control the position of the switch. The switch actuator is configured to damp tool noise and transmission of tool vibration to the tool housing.

An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The keycap is movably disposed above the base plate in a vertical direction. The light-emitting die package is disposed under the keycap and includes a plurality of light-emitting dies generating light of at least three colors. The plurality of light-emitting dies are distributed in a plane and are monochromatic light-emitting dies. Therein, among the plurality of light-emitting dies, adjacent two light-emitting dies that are arranged in a first arrangement direction perpendicular to the vertical direction emit light of different colors. Among the plurality of light-emitting dies, adjacent two light-emitting dies that are arranged in a second arrangement direction perpendicular to the vertical direction emit light of different colors. The first arrangement direction and the second arrangement direction are non-parallel.

The present utility model discloses a combined mute switch comprising a base and an upper cover arranged above the base, an accommodating cavity being formed in the combination of the upper cover and the base, a guide core being arranged in the accommodating cavity; at least one upper elastically deformable silencing member is arranged on the upper cover and on the top wall of the accommodating cavity; at least one lower elastically deformable silencing member is arranged on a lower end of the guide core; an impact force of the guide core moving downwards is damped and silenced by the lower elastically deformable silencing member; and an impact force of the guide core moving upwards to be reset is damped and silenced by the upper elastically deformable silencing member. The combined mute switch provided by the present utility model achieves a mute effect when being pressed and popped to reset.

Provided herein is a keyboard assembly that includes a keyboard substrate, a plurality of keycaps, and a plurality of lifting supports. Each keycap is connected to the keyboard substrate by using a lifting support. The keyboard substrate is connected to a bottom plate and a top plate, with the bottom plate including a key accommodation groove that further includes a concave slope. The lifting support is located in the key accommodation groove, with one end abutting against the concave slope and being capable of sliding on the concave slope. In a process in which the top plate rotates to a first specified location, the keyboard substrate is driven to move, the lifting support descends, and the keycap descends. In a process in which the top plate rotates to a second specified location, the keyboard substrate is driven to move.

An electronic device and a key coupling unit therefor are disclosed. The key coupling unit includes a key configured in a specific shape, a key guide frame configured to guide pressing of the key, and a key circuit board configured to input a signal corresponding to the pressing of the key. The key coupling unit is fixed in a settling area of a bracket. A bumper is formed to protrude from the lower part of the key circuit board. A pressing part is formed in the bracket to face the bumper of the key circuit board. A command signal of a corresponding key is transmitted to the key circuit board by converting to an electric signal if the bumper presses the pressing part. The bumper and the pressing part are located by moving in a lateral direction from the center of the settling area of the bracket.
