  This embodiment is different from the first embodiment in that a means for preventing erroneous insertion of each operation button is provided. Although the toilet lid opening / closing switch 350 and the toilet seat opening / closing switch 360 are arranged on the upper surface of the remote control device 300 in the first embodiment, the switch display is displayed on the upper surfaces of the operation buttons 351 and 361 on the upper surface of the remote control device 300 where the space is small. Because it is necessary to do so, it must be a dedicated operation button, so it must be prevented from being installed by mistake.

  In the present embodiment, as shown in FIG. 11, positioning grooves 373 are provided at different positions on the front lower ends of the operation buttons 371 and 372, and positioning ribs 349 are provided at positions corresponding to the positioning grooves 373 of the switch holder portion 343. When the operation buttons 371 and 372 are inserted by mistake, the positioning rib 349 hits the lower end of the operation buttons 371 and 372 and cannot be inserted.

  Also in the present embodiment, similarly to the first embodiment, inclined portions 351a and 361a are provided on both sides of the lower ends of the operation buttons 371 and 372, and the sliding strokes on both sides are enlarged.

  In the remote control device of the present embodiment configured as described above, the installation location of the different types of operation buttons is not mistaken.

  In this embodiment, the operation button is provided with a positioning groove and the switch holder part is provided with a positioning rib. On the contrary, the operation button is provided with a positioning rib and the switch holder part is provided with a positioning groove. The same effect can be obtained.

  As described above, since the remote control device according to the present invention has a waterproof function, it can also be applied to uses such as a remote control device and a switch device used in a washroom or kitchen.
