PROBLEM TO BE SOLVED: To provide a switch unit which allows an impactful display performance to be executed and preventing mounted electronic components from being wet with water without increasing the number of parts or complicating the process.SOLUTION: The switch unit includes: a transparent switch base 32 having openings; a transparent substrate 34 with an LED 40; a plurality of push button parts 50 placed on a transparent substrate 34 via the openings; and a top plate part. Each of the push button part unitized 50 comprises: a button body 52 with a top surface part 52a, a base part 52b and a curved deformation part 52c linking them integrally formed; a frame-shaped transparent button cover 51 covering the outer periphery of the button body 52; a first sealing part integrally formed on the curved deformation part 52c and elastically deformed so as to seal the gap between the button body 52 and the button cover 51; and a second sealing part 60 integrally formed on the outer peripheral surface of the button cover 51 and elastically deformed so as to seal the gap between the button cover 51 and the switch base 32.SELECTED DRAWING: Figure 9 |
