Waterproof Membrane Switch is a Membrane Switch whose waterproof performance can reach IP65 or even IP68. Generally used in navigation and outdoor equipment industries. Membrane Switch uses waterproof design to achieve waterproof applications, and it will continue to be used in exposed humid environments, and the life of Waterproof Membrane Switch will be longer. Thereby reducing a lot of hidden costs.
Waterproof Membrane Switch has changed our lives.
We have to admire the advancement of technology and materials, which enables our products to be expanded and improved. Waterproof Membrane Switch is one of them. Its excellent performance allows customers’ products to use Membrane Switch normally even in humid and dusty environments. Even the use of Membrane Switch in water has become a reality. The waterproof design makes the product avoid a lot of product function loss caused by moisture and dust, which leads to accidents. It is precisely because of this that our products have become more superior and practical, making our lives better and better. To say that Waterproof Membrane Switch has changed our lives, it is actually the advancement of science and technology and the advancement of materials science that have changed our lives. Make our world better and better.
Unknown advantages of WATERPROOF Membrane Switch

It can make the electrostatic shielding of ESD, EMI and RFI more excellent. Static electricity can flow out from the edges.
The actual service life is long. Due to the structure of the waterproof frame, the circuit of the product will not be easily corroded by moisture and cause the circuit to be short-circuited and oxidized.
Reasonable design even allows your Membrane Switch to be used in the deep sea.
Most Waterproof Membrane Switches are Membrane Switches with an IP rating of IP66 or above, which can be called Waterproof Membrane Switches. Excellent Waterproof Membrane Switches have obvious resistance to dust, moisture, dirt or other fine particles. Even in these types of environments, the Waterproof Membrane Switch works very well. A well-designed Waterproof Membrane Switch works even fully submerged in water without compromising its performance. Most of the regular Membrane Switch can pass IP65 – that is, there is still some simple waterproof performance, but it cannot be immersed in water without affecting its function.
Note for Waterproof Membrane Switch:
Fully waterproof even when fully submerged
Use an edge gasket between the cover edge and the mounting box
Durable enough to ensure longevity
Use specific materials that prevent damage from extreme weather or temperature
Isolate the circuit from the external environment
Easy to install or retrofit into existing equipment
2. What is the difference between the structure of the Waterproof Membrane Switch and the regular Membrane Switch?
The main difference between Waterproof Membrane Switch and Membrane Switch must be whether the circuit adopts a waterproof structure. To put it simply, as shown in the figure below, the frame structure is used to surround the inside of the line to form an island. At the same time, it is also a better design for the requirements:
The structure of the waterproof frame has the following three categories:
The regular Membrane Switch is the following structure:
3. What is the principle of waterproofing?
In the form of a frame, an island-shaped circuit is formed inside the circuit, and water droplets cannot enter the circuit through the lead wire. If the A form of the waterproof frame is selected, the water droplets cannot enter the water from the surface glue and cause the circuit function to malfunction.
4. How to improve the waterproofness of the Membrane Switch?
The buttons and LEDs need to be at least 5mm away from the edge, if possible, the farther away the better.
Choose 3M with better viscosity instead of DT Adhesive. Adhesive with better viscosity can effectively prevent Adhesive separation caused by water pressure.
Use Silicone Rubber Keypad to surround the structure below the surface glue. Conducive to the formation of island circuits to prevent moisture from entering the product and causing a short circuit.
Flex Copper Circuit can be selected. Even if the water enters in a humid environment, it will not easily cause problems in the circuit.
Since Waterproof Membrane Switch is used in the marine industry, UV-resistant materials such as XE or HP92W series materials are often selected.
As long as a reasonable design can make your Membrane Switch reach IP67 or even IP68.
5. How to test the waterproof level of Waterproof Membrane Switch?
Niceone-Keypad with IP66 and below can be tested in the factory, but IP67 and above requires a third party to test and issue corresponding documents.
When developing user interface products that require protection against continuous exposure to water, such as control panels on boats or underwater applications, you may consider the Niceone-Keypad, which has 12 years of experience and a professional engineering team. Niceone-Keypad’s engineering team works closely with customers to determine precise specifications to ensure we have the right solution for your application needs!
