In daily life, we all know that the common Waterproof and dustproof membrane switch has outstanding water resistance, and it is also very good in oil, dust, and moisture resistance. It can be used in a variety of environments. I don't know what kind of characteristics the waterproof, oil-proof, and moisture-proof membrane switch has, and what is the difference between the waterproof and dustproof membrane switch that does not have such characteristics, and why it has such outstanding effectiveness.
What kind of characteristics does the Waterproof and dustproof membrane switch have? What kind of material allows it to operate normally in the presence of rain. The main feature of the Waterproof and dustproof membrane switch is to coat a waterproof insulating layer on the conductive circuit surface so that the conductive circuit does not directly contact the pressure-sensitive adhesive layer. Otherwise, no through holes shall be opened within the range of 5m/m between the conductive lines on the upper and lower circuit surfaces, and the interlayer vent holes shall not communicate with the outside world. Then, the decrease in insulation resistance of the conductive circuit caused by the moisture absorption of the adhesive layer and the condition of water immersion and soaking into the circuit are improved.
Therefore, the Waterproof and dustproof membrane switch has good waterproof and moisture-proof functions. Therefore, it is concluded that a membrane switch that is not waterproof does not have the above requirements, and cannot have a waterproof function. The waterproof and dustproof membrane switch with strong waterproof function has the following characteristics: it is made of high-functional waterproof materials, so that the product can be used in 95% of the humid environment. There is no worry about rain, and it can be used in harsh environments.
