A keyswitch includes a cap, first and second support members slidably connected to the cap and opposite to each other, and first and second blocks formed on the cap. The cap is movable between a non-pressed position and a pressed position. The first support member abuts against the first block when the cap is located at the non-pressed position. The first block moves away from the first support member at a first gap when the cap moves downward from the non-pressed position. The first support member abuts against the cap when the cap is located at the non-pressed position, and abuts against the second block when the cap continues moving downward to the pressed position.

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.

The disclosure provides a button. The button includes at least one guiding component and a main body. The main body has at least one guiding surface. The guiding surface of the main body is slidably connected to the guiding component so as to allow the guiding component to guide the main body to move. In addition, the disclosure also provides a switch assembly and a computer host that have the button.

A rocker switching control element for electrical sliding roofs on a vehicle overhead panel has an actuation rocker formed as a switch with switching positions and is arranged on a substantially planar control panel. The actuation rocker is recessed such that it does not project beyond the panel edge region. The transition between the panel edge region and the actuation rocker is formed with the panel edge region forming over a first width a goblet-like edge set back by a first depth, and an adjoining edge, separated by a gap of width, of the actuation rocker, which edge is recessed by more than the first depth in the non-actuated state and set further back continuously over a second width by a second depth. The recess is shaped overall such that inadvertent actuation of the actuation rocker by an object significantly larger than a human finger is prevented.
