A key switch in which a pair of lever members which form a cross-link member are molded out of resin materials having different shrinkage coefficients. A shaft-receiving hole is formed in the lever member molded out of the resin material having a small shrinkage coefficient, while a linking shaft is formed on the lever member molded out of the resin material having a large shrinkage coefficient. When the key switch is structured in this way, after the lever member having the shaft-receiving hole has been molded, the resin material having a large shrinkage coefficient is hardened in a die in which the shaft-receiving hole forms a portion of a cavity in order to form the other lever member. By forming the other lever member, the linking shaft is formed in a pivotally mounted state in the shaft-receiving hole. Therefore, it is no longer necessary to link the pair of lever members by a manual operation. Accordingly, the invention provides a key switch which makes it possible to easily and reliably link a pair of lever members which support a key top in order to form a cross-link member without having to carry out a manual operation, and which makes it possible to accelerate size reduction and to carry out an assembly operation with greater ease. The invention also provides a method of producing the same.
