Embodiment
First embodiment
At first consult Fig. 2, this figure is the schematic diagram of first embodiment in expression the utility model.As shown in the figure, illuminated key switch of the present utility model mainly comprises a light source L, a leaded light component N, a film M1 ' and a distance member M3 '.Wherein, above-mentioned leaded light component N has light conductivity, and in order to support whole key switching structure; In addition, above-mentioned distance member M3 ' is positioned between film M1 ' and the leaded light component N, and limits a space 20 ' jointly with film M1 ', leaded light component N.Above-mentioned film M1 ' is made by light transmissive material, passes in order to light yet the holes structure also can be set.Wherein, it is made that leaded light component N can be hard transparent plastic, acryl or glass; In present embodiment, film M1 ' material is known polyester film (Polyester Mylar), and leaded light component N material is a hard transparent plastic.
In particular, be provided with one first conductive part P0 in film M1 ' bottom surface, and be provided with the second conductive part P1 ', P2 ' in leaded light component N end face, wherein the first conductive part P0 and the second conductive part P1 ', P2 ' are arranged in space 20 ', and connect the printed circuit (not icon) that is positioned on film M1 ' and the leaded light component N respectively.As previously mentioned, the first conductive part P0 and the second conductive part P1 ', P2 ' keep separating and are off state under normal condition.Yet, when the user pushes the end face of film M1 ', make that upper film M1 ' moves down and cause the above-mentioned first conductive part P0 and the second conductive part P1 ' that is positioned at leaded light component N surface, P2 ' electrically contacts and be conducting state.
