PURPOSE:To improve the degree of freedom of a layout when arranging closely by fixing a back light type display panel on the upper surface side of a substrate, fixing a push button switch on the lower surface side, and moreover making a control plate operating the push button switch to be supported in a vertical motion freely on the upper surface side of the substrate in parallel to the upper surface side. CONSTITUTION:A display panel 3, in which two or more pieces of information can be displayed on the display surface facing upward, is fixed on the upper surface side of a substrate 2, and a push button switch 4 is fixed on the lower surface side of the substrate 2 with the head part of the switch 4 facing downward. Moreover, a control plate 5, which is having a transparent window and suppoted in a vertical motion freely via a spring, is provided on the upper surface side of the substrate 2 in parallel to the upper surface side remaining an adequate action stroke in the space to the panel 3. The plate 5 is integrally danglingly projected from the side edge, and having a L-shaped operation arm 8 making the tip part of the plate 5 to act the switch 4 with interlocking the vertical motion of the plate 5. This makes it possible to effectively use the upper surface side of the substrate 2, and to expand the degree of freedom of a layout when arranging a switch etc., closely.
