Further, the surfaces of the inner case 21 facing the same direction as the "back surface", "front surface", and "side surface" of the outer case 31 are also referred to as "back surface", "front surface", and "side surface", respectively.

For example, assuming that the call switch 10 is installed in the bathroom, in this case, the call switch 10 may be exposed to hot water from a shower or bathtub during bathing, or shower water may be applied during cleaning. On the other hand, in the present embodiment, the call switch 10 has an inner case 21 in which the inner space 57 is a substantially sealed space by the seal member 53, the seal member 52, and the seal member 54, and an outer case accommodating the inner case 21. Since it has a double housing structure including the case 31, it is possible to prevent hot water or water from entering the inner case 21 accommodating the wireless portion 56. As a result, the waterproof performance of the call switch 10 can be improved.

With reference to FIG. 7, the boundary portion 61 between the upper case 22 and the lower case 23 appears on the outer surface of the inner case 21, and the boundary portion 62 between the upper case 32 and the lower case 33 appears on the outer surface of the outer case 31. Is appearing. The boundary portion 61 is provided on the side surface of the inner case 21. The boundary portion 61 extends in a straight line on the side surface of the inner case 21 and goes around. The boundary portion 62 is provided on the side surface of the outer case 31. The boundary portion 62 extends in a straight line on the side surface of the outer case 31 and goes around the boundary portion 62.

The boundary portion 62 is provided at a position not facing the boundary portion 61. The boundary portion 62 is provided at a position deviated from the boundary portion 61 in the thickness direction of the inner case 21 and the outer case 31. The boundary portion 62 is provided at a position deviated from the boundary portion 61 toward the front side of the outer case 31 in the thickness direction of the inner case 21 and the outer case 31. The boundary portion 62 extends parallel to the boundary portion 61.

With reference to FIG. 3, the boundary portion 67 of the opening edge of the push button 26 and the button arrangement hole 27 appears on the outer surface of the inner case 21, and the push button 36 and the button arrangement hole 27 appear on the outer surface of the outer case 31.

The boundary portion 66 is provided in front of the outer case 31. The boundary portion 66 has a circular shape.

The boundary portion 66 is provided at a position not facing the boundary portion 67. The boundary portion 67 is arranged inside the boundary portion 66 having a circular shape. The boundary portion 66 is provided at a position not facing the boundary portion 68. The boundary portion 68 is arranged outside the boundary portion 66 having a circular shape.

With reference to FIGS. 3 and 7, the boundary portion 62 and the boundary portion 66 appearing on the outer surface of the outer case 31 may be any of the boundary portion 61, the boundary portion 67, and the boundary portion 68 appearing on the outer surface of the inner case 21. It is provided at a position that does not face each other.

In the present embodiment, by arranging the inner case 21 and the outer case 31 by shifting various boundaries assumed as water entry lines, water or hot water that has entered the outer case 31 can be directly discharged to the inner case 21. It is possible to prevent it from hitting the water entry line. As a result, the waterproof performance of the call switch 10 can be further improved.

In the present embodiment, since the optical path rod 38 is heat-welded to the outer case 31, this portion cannot serve as the water entry line in the outer case 31.

FIG. 8 is a cross-sectional view showing an outer case along the line VIII-VIII in FIG. With reference to FIG. 8, the boundary portion 62 between the upper case 32 and the lower case 33 of the outer case 31 has a cross-sectional shape extending non-linearly between the outer surface 31m and the inner surface 31n of the outer case 31. More specifically, the boundary portion 62 has a cross-sectional shape that bends and extends like a crank between the outer surface 31m and the inner surface 31n of the outer case 31.

The boundary portion 62 is not limited to the crank shape shown in FIG. 8, and may have, for example, a cross-sectional shape that bends and extends in a zigzag shape, a cross-sectional shape that forms a meander shape, and a cross-sectional shape that extends in a curved shape.

Has a shape.

According to the combined structure of the upper case 32 and the lower case 33 shown in FIGS. 8 and 9, water or hot water that hits the outer surface 31 m of the outer case 31 is less likely to enter the outer case 31 through the boundary portion 62. Therefore, the waterproof performance of the call switch 10 can be further improved.

FIG. 10 is a rear view showing an outer case seen from the direction indicated by the arrow X in FIG. With reference to FIG. 10, through holes 91 to 100 are formed in the outer case 31. The through holes 91 to 100 are provided so as to communicate between the external space and the space inside the outer case 31 accommodating the internal switch 20. The through holes 91 to 100 are provided so as to penetrate the outer case 31 in the plate thickness direction.

According to such a configuration, the hot water or water that has entered the outer case 31 is discharged to the outside through the through holes 91 to 100, so that the waterproof performance of the call switch 10 can be further improved. At this time, since a plurality of drainage holes are prepared, it is possible to prevent the pressure inside the outer case 31 from increasing due to the intrusion of hot water or water. As a result, it is possible to more reliably prevent hot water or water from entering the internal switch 20.

When viewed from the direction along the pressing direction of the push button 36 (in FIG. 10, when viewed from the back side of the outer case 31), the through holes 91 to 100 are formed on one side and the other side of the push button 36.
