<P>PROBLEM TO BE SOLVED: To provide a sheet-like switch allowing a moving contact to be surely and smoothly connected/separated to/from a fixed contact by reducing noise in pressing the switch. <P>SOLUTION: This sheet-like switch is provided with: a circuit board 1 formed by arranging a contact electrode 3 on a part of a surface of an insulation board 2; a reversibly-deformable dome-shaped moving contact 5 arranged oppositely to the contact electrode 3; a support sheet 6 arranged on the dome outer surface side of the moving contact 5, and reversibly-deformably supporting the moving contact; a pressing operation plate 7 arranged on the support sheet; and a pressing piece 9 made of a synthetic resin and arranged on the support sheet side of the pressing operation plate; and is characterized in that the pressing piece 9 is arranged at a position superposing the contact electrode and the dome top part 5a of the moving contact; and the support sheet 6 has a roughened layer 6a formed on a surface corresponding to at least the pressing piece. <P>COPYRIGHT: (C)2008,JPO&INPIT |
