ABSTRACT:
A key switch device has a cap support that supports a key cap on a base. The cap support includes intersecting first and second frames which are connected pivotally to each other. The first frame has a pair of through holes, whereas the second frame has a pair of retaining pins for connection with the through holes. Each retaining pin has an outermost head, an inner neck part and a shoulder formed between the outermost head and the inner neck part. The first and second frames are connected to each other by inserting each retaining pin into the corresponding through hole until the outermost head projects outwardly of the through hole and the shoulder engages an outer side of the first frame.
