Title: WATERPROOF MEMBRANE SWITCH
Abstract:
Provided is a waterproof membrane switch, which comprises a rubber button (1), an upper circuit board (2), a first sealant layer (3), a separator layer (4), a second sealant layer (5), a lower circuit board (6) and a waterproof cable (7). The upper circuit board (2) is provided with a groove (21). The rubber button (1) is adhered in the groove (21) on the upper circuit board (2) by waterproof glue. The upper circuit board (2) is adhered to an upper part of the separator layer (4) through the first sealant layer (3). The lower circuit board (6) is adhered to a lower part of the separator layer (4) through the second sealant layer (5). The upper circuit board (2) is provided with a first upper contact (22) and a second upper contact (23). And the first upper contact (22) is electrically connected to the second upper contact (23). The lower circuit board (6) is provided with a first lower contact (61) and a second lower contact (62). The waterproof cable (7) comprises two wires, and the first lower contact (61) and the second lower contact (62) are electrically connected to the two wires respectively. The waterproof membrane switch has a simple structure, is easy to use, and can effectively prevent water and dust into the membrane switch, so as to enhance service life of the membrane switch.
