ABSTRACT:
A switch to be used mainly for controlling a variety of electronic devices in automobiles, and a method of manufacturing the same switch are disclosed for providing a switch free from positional deviation in its display section and easy to manufacture. Operating units having no display sections are mounted to a housing, then the shapes of each one of the operating units are recognized by a control circuit. An upper jig and a lower jig are moved for a laser beam device to remove a non-translucent section and expose parts of a translucent section, thereby forming the display sections. This structure allows eliminating positional deviation of the display sections and also requiring no visual checks done for confirming the display sections in manufacturing.
