The static contact plate and the moving contact plate are both arranged on the pedestal; and a welding pin of the static contact plate and a welding pin of the moving contact plate both extend out of the pedestal. The upper cover is installed on the pedestal. The key is arranged on the pedestal and is exposed out of the upper cover; and a reset spring (16) is arranged for the key. The upper cover is a light-transmitting body; the bottom of the upper cover extends in an integrated mode to form a light guiding column (20); a light source (27) is arranged for the light guiding column; and the light of the light source is transmitted by the light guiding column and then is emitted by the surface of the upper cover. Therefore, by means of the integrated design of the upper cover and the light guiding column, the two can be arranged by injection molding once. The keyboard switch can be manufactured easily; the cost is low; the assembling procedures are simplified; and the assembling is simpler and more conveniently. Meanwhile, the whole upper cover can transmit light; the light-transmitting area is increased; and the light-emitting effect is improved to the great extent.

Abstract
Disclosed is a luminous keyboard switch, comprising a base, a fixed contact sheet, a movable contact sheet, an upper cover, and a button used to control the contact or separation between the movable contact sheet and the fixed contact sheet. The fixed contact sheet and the movable contact sheet are both arranged on the base. A welding pin of the fixed contact sheet and a welding pin of the movable contact sheet both extend out of the base. The upper cover is mounted on the base. The button is arranged on the base and the upper cover is exposed. A reset spring for the button is provided. A light guide plate is arranged below the base. A light source is provided corresponding to the light guide plate. The base and the upper cover are each correspondingly provided with a light through hole extending downwards to the light guide plate. The light of the light source is emitted outwards through the light through hole after being transmitted by the light guide plate. By means of the light guide plate, the light through hole, and other structural arrangements, it is achieved that a plurality of keyboard switches share one light source, therefore the usage amount of light sources can be greatly reduced, the production costs can be saved, and at the same time, the maintenance and the management thereof can be facilitated.
