PROBLEM TO BE SOLVED: To easily assemble link members and a holder member by locking the lower end of a first link member in a third locking part of the holder member, locking the lower end of a second link member in a fourth locking part of the holder member, and fixing a circuit board and a supporting member to the lower side of the holder member. SOLUTION: In a key switch 1, a turning locking part 15 and a sliding locking part 16 are installed on the bottom surface of a key top 2, and a sliding locking groove 28a and a turning locking groove 27a are formed in a holder member 7, in the lower diagonal position of the turning locking part 15 and the sliding locking part 16. A first link 4 and a second link 5 are locked in the turning and sliding locking grooves of the holder member 7, and guide the vertical motion of the key top 2. Two contacts of a circuit board 9 are switched according to the vertical motion with conductive rubber 30, and after the first and second links 4, 5 are locked in the holder member 7, the circuit board 9 and a reinforcing plate 10 are fixed to the holder member 7. The first and second links 4, 5 are easily assembled with the holder member 7. |
