Switch and method of manufacturing the same

Abstract

The present invention provides a switch which is easy to manufacture and is free from positional displacement of a display part, and which is mainly used for controlling various electronic devices in automobiles, and a method of manufacturing the same. To this end, the operating body without the display part is assembled on the box body, and then the control circuit recognizes the shape of each operating body, moves the upper jig or the lower jig, removes the opaque part through a laser device, and forms a display in which the light-transmitting part is exposed department. In this way, not only is there no positional displacement of the display unit, but also the display does not need to be visually recognized during assembly.

Description

technical field [0001] The present invention relates to a switch mainly used for controlling various electronic devices in automobiles and a method for manufacturing the same. Background technique [0002] In recent years, in automobiles, a so-called steering switch is commonly installed near the steering wheel, and the switch is operated with fingers while holding the handle to control electronic equipment such as audio equipment and air conditioners, so that there is no misoperation and easy operation. [0003] Such a conventional switch and its manufacturing method will be described with reference to FIGS. 9 to 11 . [0004] Fig. 9 is an exploded perspective view of such a conventional switch. As shown in the figure, such a conventional switch includes substantially box-shaped operating bodies 1 to 3 made of insulating resin, and a case 4 similarly made of insulating resin. A plurality of (three in FIG. 9 ) through-hole portions 4A are formed on the upper surface of the...

Problems solved by technology

[0022] However, in the conventional switches described above, when the upper surfaces of the operating bodies 1 to 3 are irradiated with laser light, and the opaque portions are removed in a predetermined shape to form the display portions 1A to 3A, variations occur in the sizes of the operating bodies 1 to 3, Or there is looseness between the inserted holding part 9A, etc., which may cause positional displacement of the display parts 1A to 3A.

[0023] In addition, when mounting the operation bodies 1 to 3 with different display shapes on the case body 4 , it is necessary to attach and assemble the operation bodies 1 to 3 on top without confusing the order of the arrangement while visually viewing each display shape. , the center, and the lower through-hole portion 4A, so there is a problem that it takes time to manufacture and the cost of the switch becomes high.
