IP65 Waterproof Membrane Switch
Waterproof Membrane Switch is mainly characterized by coating a waterproof insulation layer on the conductive line surface so that the conductive line does not directly contact the pressure sensitive rubber layer. In addition, no holes shall be opened within 5m/m of the distance between the up-and-down road surface and the conductive line, and the interlayer air holes shall not be communicated with the outside world. Thus, the insulation resistance drop of conducting circuit caused by the moisture absorption of rubber layer and the impregnation and penetration of water into the circuit are improved. Therefore, it has the advantages of good waterproof and moisture-proof performance. Therefore, not waterproof membrane switch is not with the above requirements, but also can not have waterproof performance. The waterproof film switch has the characteristics of: the use of high-performance waterproof material processing, so that the product is used in 95% of the wet environment. No worries about rain, can be used in harsh conditions.
