PURPOSE:To improve the visibility of operation, and reduce the number of parts and the cost by manufacturing a recessed part to be loaded with a light emitting element for display and an elastic body, which is arranged adjacent to the recessed part and which elastically supports a pair of electrodes freely to separate, with the MID method. CONSTITUTION:A back-lighted switch device preforms the display of ON/OFF switching of an electrical contact 11 with the light emission of a light emitting element 12 for display, which is arranged adjacent to the contact 11 through a package 13. The contact 11 consists of an elastic body 27, which elastically supports a first tip 25 and a second tip 26 freely to separate, and a first electrode 28 and a second electrode 29, which are respectively formed in the tips 25 and 26, and the ON/OFF of the contact 11 is switched electrically by the existence of the contact of both the electrodes. A three-dimentional wiring part 22, which is fitted to the package 13 and loaded with the element 12, and both the electrodes 28, 29 are formed three-dimentionally as a molding product with the chemical plating or the like (MID method). Respective Parts are formed integrally as for as possible to make a device compact and reduce a cost. |
