Abstract | PURPOSE:To provide a keyboard switch having dust-proofing and water-proofing structure in which a low cost membrane contact of a single-layer structure can be used, for which assembling processes are simplified, and in which abnormal sound is not generated even when a key top is pushed diagonally. CONSTITUTION:A resin frame 3 is positioned on a surface of a membrane contact 2 laminated on a reinforcement plate 1, a contact rubber 5 is fixed to a forward end of a key stem 4a of a key top 4 guided by a slide cylinder 3a of the resin frame 3, and the membrane contact 2 is opened/closed by the contact rubber 5. In this keyboard switch, a click rubber sheet 6 is laminated on a surface of the resin frame 3, and a click part 6a of the click rubber sheet 6 is applied to a lover surface of the key top 4. |
