The key top comprises a bottom surface (241) and a central protruding post (25) arranged at the bottom surface (241), and the central protruding post (25) is inserted in the hollow cylinder (21). A silicone rubber dome (26) is located on the electrically conductive flexible sheet (23), and the silicone rubber dome (26) has a raised portion (27) configured to hold the central protruding post (25), such that the key top (24) does not contact the top portion (22) when springing back after pressed. |
