PURPOSE:To improve the degree of design freedom and enable diversified designs to be performed by providing a switch substrate and switch rubber plate which are made separate and independent from module body to one module and directly fixing these to a case part. CONSTITUTION:A separate and independent switch substrate 2 is superposedly disposed on the top plane part of a module body 1. This switch substrate 2 is provided with an escape hole 2a of the digital display panel protruding part 1a of the module body 1. A switch rubber plate of conductive material is disposed on the switch substrate 2. An escape hole 3a is provided to the switch rubber plate 3 as well. As the buttons 5 built into the cover glass 4 are pushed down, the switch rubber plate 3 deforms and contacts and electrically conducts to the switch substrate 2 and is thereby connected to the module body 1 via connctor 8, whereby function operations such as of calculator, world time, etc. are accomplished. As the hand is released from the buttons 5, the swithes are cut off by the elastic force of the switch rubber plate 3. |
