membrane switch waterproof
Waterproof membrane switches are electronic components specially designed for use in wet or liquid-exposed environments. They use special materials and structural designs that effectively prevent moisture, dust and other contaminants from entering the interior of the switch to ensure its normal operation. Conventionally, the waterproof rating of membrane switches can reach IP65; if there are special requirements, we can customize waterproof membrane switches of IP67 and IP68 levels for customers.
As an industry leader with 20 years of R&D and manufacturing experience, SOUSHINE has always been committed to the iterative upgrading of membrane switch technology, and has been deeply involved in the design of interactive interfaces in the fields of medical equipment, household appliances, etc., and has provided customised solutions for the world’s top brands, including Panasonic and Haier.
The Mechanisms and structures of membrane switch waterproof
1. Surface layer (Graphic Overlay)
Material: PET or PC substrate.
Function: Display key identification (e.g. numbers, letters, icons), provide tactile feedback (e.g. bumpy key design).
Characteristics: Wear-resistant, chemical-resistant, UV-printed or hardened surface.
2. Circuit Layer
Material: silver printed circuit & FPC
Function: Conduct the electrical signal triggered by the key.
Characteristics: On-resistance ≤100Ω, support analogue/digital signal output.
3. Spacer Layer
Function: Forms an air gap through laser etching to ensure insulation when the key is not triggered.
Characteristics: Withstanding voltage ≥100V DC, adaptable to -40℃ to +85℃ environment.
4. Adhesive Layer
Function: Secures the membrane keypad to the device panel and provides IP67 sealing protection.
Characteristics: Adaptable to extreme environments, prevents liquid penetration and dust contamination.

What kind of waterproof membrane switch service can we offer you?
We provide you with high quality, after-sales guaranteed keypad membrane products.
In the beginning, after receiving the customer’s enquiry, our sales engineers will summaries the information in the shortest possible time and make a good evaluation, and discuss the feasibility of the proposal with the production engineers within 12 hours and make suggestions for modification to the customer’s evaluation.
After receiving SOUSHINE’s feedback on the Membrane switch project, the customer will give their opinion and confirm their intention. SOUSHINE will build a production order for the customer within four hours after receiving the customer’s confirmation.
For regular products, our professional drawing engineers will draw the schematics and renderings of the products within 8 hours for the customers to confirm the size and effect, and SOUSHINE promises to provide customers with countless free modifications of the drawings after building the file.
After the customer confirms the drawing, SOUSHINE’s planning and scheduling center will prepare the raw materials for the production of the product and enter the production workshop according to the production plan. It is expected that the production and testing of regular products will be completed within 3-5 days.
Frequently Asked Questions about Membrane Switches
What parts of my membrane switch product can SOUSHINE customise?
As a professional membrane switch manufacturer, SOUSHINE supports customised membrane switches with four major components. Including the surface layer of Grahpic overlay, we provide the material choices of PET, PMMA, and PC, and for the circuit layer, we support both PET and FPC choices. As for the adhensive layer, we support more than 20 varieties and different prices.
In addition, we can provide customers with customised price plans to solve the pain points of customers’ first customisation.
What is the difference between PMMA,PC,PET as Graphic overlay and which one do you recommend?
PMMA and PC as Graphic overlay in the most common materials, and PET compared to the most important is that PET can only produce less than 0.5MM below the product; and PMMA and PC can produce thick overlay, such as 1.0mm ~ 5.0mm. and PMMA compared to PC, the material is more hard and brittle, PC bending is not easy to break, but the It is easy to oxidise and yellow, so the specific production and design still need to be based on product characteristics.
What is the biggest difference between PET circuit and FPC ?
The most essential difference is the difference in material. Since it is made of copper as the substrate, the price of FPC line is much more expensive than that of PET substrate. But relatively speaking, the life of FPC will be longer, generally speaking, 5-10 years of service life is the most basic. In addition, FPC material can be used in the environment of minus 20 degrees and above 80 degrees.
How long does it take to produce and design a typical membrane switch?
SOUSHINE has a professional production team and design and engineering team, after receiving the order. Schematics and renderings can be provided within 4 hours at the earliest. We can produce samples of regular products within 48 hours and large orders within 5 days.
What payment method does SOUSHINE support?
SOUSHINE supports the mainstream payment methods in the market, including bank transfer, PAYPAL payment, Visa transfer, alipay and so on. In addition, we also have a Hong Kong branch to handle payment collection.
What about SOUSHINE's after-sales service?
SOUSHINE is 100% responsible for the products it produces for 100 years. We are committed to providing countless revisions at the design drawing stage, before confirming the samples.
