  • Patent number: 12177995
    Abstract: A remote control with a waterproof function includes a case including an upper case having button holes and a lower case assembled to the upper case at a lower portion of the upper case, a printed circuit board PCB embedded between the both cases, and a rubber keypad embedded in the case so as to be positioned between the upper case and the PCB and having buttons passing through the button holes. Barriers protruding upward or downward along the edges of the rubber keypad are provided, and when the both cases are coupled with the rubber keypad interposed therebetween, the side portions of the lower case and the lower ends of the barriers are in close contact with each other and the inner surface of the upper case and the upper ends of the barriers are in close contact with each other, thereby providing waterproof function.
