CROSS TYPE KEY SWITCH

PROBLEM TO BE SOLVED: To simplify the assembling work of a cross type key switch by hanging protrusions passing through a retaining plate and respectively setting moving contacts on the low ends of the protrusions arranged in cross four directions, whereas elastically setting the other protrusions on a board so as to energize a key top upward. SOLUTION: A rubber sheet 25 is sandwiched between a key top 11 and a retaining plate 24 capping fitted to the bottom face of the key top 11. Eight protrusions 28, 28... are rotation-symmetrically arranged on the rubber sheet 25 via a center hole 27 and are respectively hung under a retaining plate 24 via the through hole 29 of the retaining plate 24. Out of the protrusions 28, moving contacts 10 are disposed on the low ends of the protrusions 28a arranged in the cross four directions, and the moving contacts 10 are up and down faced to the fixed contacts 4 on a board 3 surface. Whereas the other protrusions 28b are elastically fitted to a board 3 so as to energize the key top 11 upward.
