As shown in FIG. 7, a display window of a conventional electronic switch has a printed circuit board 17 inserted into a metal housing 1, and a display element 18 is fixed to the printed circuit board 17. Also, on the wall of the housing 1,
The through hole 2 is provided at a position facing the display element 18. On the other hand, a columnar display rod 19 having translucency is provided, and the display rod 19 has a large diameter D2 slightly larger than the diameter D1 of the through hole 2 and a depth L2 shorter than the wall thickness L1 of the housing 1.

あった。This conventional method of forming a display window requires a specially shaped display rod 19 having a flange portion 20 for press-fitting, which not only complicates the processing technique. In order to prevent the display rod 19 from coming off the housing 1, a large force is required for press-fitting the display rod 19 into the housing 1, and the manufacturing apparatus becomes complicated in relation to the housing 1. Further, the through hole 2 is required to have high dimensional accuracy, and moreover, the press-fitting area of the display rod 19 to the housing 1 is required, so that the length L2 of the large diameter portion 20 and the wall thickness L1 of the housing 1 are increased. Further, when the diameter of the housing 1 is small, the lower portion L3 of the display rod 19 is deeply inserted into the housing 1, so there is a fear of colliding with the display element 18 mounted on the printed circuit board 17. Further, when the tip portion of the display rod 19 is flat, there is a problem that the filler 21 such as the epoxy resin filled in the housing 1 is cracked.

A receiving member having a shape along the inner peripheral surface of the housing is arranged so as to close the through hole, and the through hole is filled with a translucent ultraviolet curable resin from the outside of the housing,
This is a method of curing the ultraviolet curable resin by irradiating the ultraviolet curable resin with ultraviolet rays, so that it is not necessary to make the thickness of the housing particularly thick, and therefore, when the outer shape of the housing is made the same, Due to the difference, the inner diameter of the housing is increased, and the electronic circuit board accommodated in the housing has a mechanical allowance, the housing is lightweight, and the UV curable resin is easily penetrated by utilizing its fluidity. Since it can be injected into the hole, it does not require high dimensional accuracy like the conventional forming method, and it does not require high accuracy even for the through holes, which makes it easy to process the housing, and thus it is difficult to process such materials as stainless steel. It can be made of any hard material. In addition, since the display window is molded and protrudes into the peripheral portion of the through hole, the sealing property is improved.

Insert the rod, place the inner heating plate and the outer heating plate inside and outside the housing, sandwich the housing with these heating plates, heat deform the rod, and project this rod to the peripheral edge of the through hole. Since the display window is formed by doing so, it is not necessary to increase the thickness of the housing so that when the outer shapes of the housing are made the same, the difference in the thickness increases the inner diameter of the housing. At the same time, there is a mechanical allowance in the electronic circuit board housed in the housing,
In addition, the housing is lightweight, and the resin rod does not require high dimensional accuracy as in the conventional forming method, and the through holes do not require particularly high accuracy, so it is difficult to process the housing, such as stainless steel.
