Abstract
An illuminated keyswitch structure is provided. A base plate includes plural openings and plural rib portions separating the openings. A drive circuit board is disposed under the base plate. A spacer having a through hole is disposed underneath the base plate and above the drive circuit board. A light-emitting part with low illuminance is disposed on the drive circuit board and in the through hole, and the light-emitting part vertically corresponding to one of the openings of the base plate. A light-permeable covering structure includes a first covering layer and a second covering layer. The second covering layer vertically corresponds to the light-emitting part and said corresponding opening of the base plate. The second covering layer blocks at least partial light of the light-emitting part toward said corresponding opening to reduce illuminating intensity provided there through.
