DESCRIPTION OF THE INVENTION (4) The height of the light-transmitting projections 213a may be the same as the thickness of the bottom plate 211. The functions of the light-transmitting projections 2 13a are such that the film wiring board 2 0 9 is not recessed into the light-transmitting holes 211a due to the pressure. The key cap 201 is permeable to the central region 2 0 1 a at its top, and its central region 2 0 1 a corresponds to the top end position of the elastic member 207 and is located within the range of the central region 201a, which is printed. There are numbers or patterns. For the light emitted from the light guide plate 23, please refer to the light-bearing head of the third figure. The line represents the light, and the light path is through the light-transmitting holes 211a of the bottom plate 21 and the light-transmitting holes. The protrusion 213a, the elastic members 207 reach the central region 201a of the top of the keycaps 201, when the light reaches the central region 2 0 1 a, at this time, the text printed by the key cap 201 The number or pattern will show the effect of receiving light. The material of the above-mentioned bottom plate 2 1 1 of the present invention can be manufactured by using a thin metal plate. The above-mentioned thin film circuit board 209 can be manufactured by using a light transmissive material. The frame 2 0 3 described above can be a frame of a scissor structure. The above-mentioned keycap 201 is not permeable to light except that the central portion 201a is permeable to light. The light guide plate 213 and the light-transmitting protrusions 213a of the present invention can be manufactured by integral molding. The light-transmitting button switch structure 20 of the present invention can be used as an important component of the transparent keyboard. The keycap 2 0 1 on each button of the transparent keyboard of the present invention is only in the central region 2 0 1 position. It is used to present the effect of printing digital numbers or pattern lights, and the rest of the light-transmissive keyboard does not have this light effect.
