<p>PROBLEM TO BE SOLVED: To provide a force detector not changing output of a joystick in turning on a switch mechanism and preventing the switch mechanism from being turned on in operation of the joystick. SOLUTION: An operation button 2A arranged in a base board 1 can be pressed inward, while two switching conductive parts SD1 and SD2 and electrodes Dx+ and Dx- surrounding the conductive parts and arranged at equal angular intervals are arranged on the base board 1. A flat conductive part SD is formed on the face facing the switching conductive part SD1 and SD2 in the operation button 2A, while an elastic displacement plate 3, which can be pressed inward, is arranged between the operation button 2A and the base board 1 opposedly to the electrode. When the operation button 2A is pressed inward vertically, the switching conductive parts SD1 and SD2 are electrically connected to each other via the conductive part SD, so that a switch is turned on. When the operation button 2A is pressed inward slantingly, the elastic displacement plate 3 is pressed by an operation button 2A constituting lower wall so as to be brought close to the electrode side, and consequently, electrostatic capacity in the slanting direction is changed.</p> |
