PURPOSE:To obtain a high-reliability wrist watch with a computer where no malfunction is generated, by bringing a contact into contact with an electrode through the slit of the insulating layer between the contact consisting of conductive elastic materials and the module substrate electrode when a pressure over a fixed value is applied to a key. CONSTITUTION:When key 10 is depressed which corresponds to operation keys 1 and 2 for watch and computer on the watch surface and moves vertically, key switch main body 30 is depressed to bring contact 31 consisting of conductive elastic materials into conatct with insulating sheet 60. When key 10 is depressed furthermore, contact 31 is deformed elastically and has a part protruded into slit 61 provided in insulating sheet 60 and brought into contact with electrode 51 provided on substrate 50; and when key 10 is released, contact 31 is returned to the original position by restoration force of switch 30. As a result, the input dependent upon everyday movements such as arms folding can be prevented, and a wrist watch with a computer where no malfunction is generated can be obtained. |
