A key switch unit of synthetic material includes a housing and at least one key top connected to a spring section. The housing, key top and spring section are injection molded of one piece. The key top is folded back, whereby the spring section and the key top are disposed opposite one another. The key top and the spring section are elastically movable relative to the housing. By elastically pushing the key top against the spring section, the spring section is elastically displaced toward a switch element. |
