The present invention relates to an elevator button with a waterproof function, wherein when water penetrates between an outer housing and a button unit, the water is blocked by a waterproof cover sealing and covering a front surface of a board so as to prevent the water from penetrating the board, and when a buffer protrusion of the waterproof cover, which is pressed by a touch protrusion of the button unit when the button unit is pressed, presses and operates a tact switch on the board so as to prevent the external pressure from being applied to the tact switch. According to the present invention, a waterproof cover is installed to surround the outer surface of the board, a front surface of the board is sealed and covered by the waterproof cover, and a sealing cover of the board prevents the generation of a gap between the board and the waterproof cover. Accordingly, there is no risk of water flowing into the board. Since the board is waterproof with the waterproof cover, there is no risk that the board will be electrically damaged. Since the tact switch is covered with the buffer protrusion of the waterproof cover, there is no risk of water penetrating the tact switch and causing electrical damage. In particular, when the buffer protrusion is pressed by the touch protrusion, the tact switch is pressed and operated so as to buffer the external pressure applied to the tact switch. Accordingly, the damage rate of the tact switch is significantly reduced, and the elevator button can be used for a long time. Therefore, product reliability can be improved.

    본 발명은 방수기능을 갖는 엘레베이터 버튼에 관한 것으로, 외부하우징과 버튼부 사이로 물 침투시, 이 물이 기판 전면을 밀폐 커버한 방수커버에 의해 차단되어, 기판으로 물이 침투되는 것이 방지함과 동시에, 버튼부 누름시 버튼부의 터치돌기에 눌림되는 방수커버의 완충돌기가 기판의 택트스위치를 누름 작동시켜, 택트스위치에 외압이 가해지는 것을 완충한다. 본 발명에 따르면, 방수커버가 기판 외면을 감싸도록 설치하여, 기판 전면이 방수커버에 의해 밀폐 커버되고, 이 기판의 밀폐 커버로 기판과 방수커버 사이의 틈새 발생이 방지되어, 기판으로 물이 유입될 우려가 없으며, 방수커버로 기판을 방수하여 기판이 전기적 손상으로 손상될 우려가 없고, 방수커버의 완충돌기로 택트스위치를 커버하여 택트스위치에 물이 침투되어 전기적 손상일 일으킬 우려가 없으며, 특히, 완충돌기가 터치돌기에 눌림되면서 택트스위치를 누름 작동시켜, 택트스위치에 가해지는 외압이 완충되고, 이에따라, 택트스위치 손상률이 현저히 저하되면서, 엘레베이터 버튼을 장기간 사용할 수 있어, 제품의 신뢰성이 향상되는 장점이 있다.
