Waterproof Membrane Switch – SY01
Waterproof Membrane Switches
If there is no properly sealed waterproof membrane switch or waterproof keyboard, your electronic products will be at risk of moisture, dust, dirt, and other fine particles invading. This may damage your membrane switch keyboard equipment, leading to shortages and failures, and it is not cheap to repair.
Before designing a waterproof membrane switch or a waterproof keyboard membrane, be sure to pay attention to the difference between a waterproof membrane switch and a waterproof membrane switch: a waterproof rubber keyboard and a membrane switch can only resist water exposure, such as vertical splashing or overflowing. However, waterproof switches and keyboards can withstand complete immersion in water or spray flushing.
Using a waterproof membrane switch is the best way to protect your investment and save money, time, and stress.
CE Certification Waterproof Membrane Switches
Shanyo produces waterproof membrane switches and keyboard films that comply with the International Electrotechnical Commission (IEC) standard IP68. Components manufactured according to this standard can be soaked in fresh water at a depth of 1.5m (4.9 feet) for up to 30 minutes and can withstand dirt, dust, sand, and humid environments.
We recommend using an IP68 waterproof rubber keyboard in the following applications：
- Boat/boat
- trailer
- truck
- All-terrain vehicle
- Handheld electronics
Our rubber membrane switches are made of high-grade silicone rubber and conductive carbon particles or non-conductive rubber actuators. Through the compression molding process, an angled net is formed around the keyboard, which collapses whenever the user presses a key. This protective webbing provides users with a variety of benefits.
China Waterproof Flexible Membrane Switches Protect against Damage from Water, Dust, and Micro-Particulate
The most important role of waterproof membrane switches is to protect your precious electronic equipment from further damage. The stamper silicone rubber of the rugged membrane switch can be moisture-proof, thereby extending the service life of the equipment.
Cheap Waterproof Membrane Switch
In addition to its waterproof ability, the low price makes rubber keyboards and switches such a popular choice. These components are often cheaper than waterproof mechanical switches and can provide the functions you need at a cost-effective price.
Membrane Switch Waterproof Resistance to Extreme Temperature And Aging
Silicon is not only very suitable for waterproof and dustproof particles but also plays a good role in heat resistance and long-term use. Moisture resistance and chemical resistance can slow down deterioration, making silicone rubber keyboards and waterproof membrane switches a huge investment.
Customized Waterproof Flexible Membrane Switches Have Appearance Options And A Tactile Feedback
Waterproof membrane switches and rubber keyboards can be designed in a variety of different shapes, sizes, and colors to meet your needs. They provide flexibility in terms of rubber hardness and keyboard surface design. You can also create your favorite tactile feedback style, including a 3-dimensional keyboard and a firm tactile response.
The keyboard film adopts a smooth silicone rubber keyboard, which increases comfort
Keyboards and membrane switches are conducive to user interaction, and silicone rubber is a good way to improve the user experience. Unlike plastic buttons, rubber buttons are soft and more comfortable to press.

Non-tactile membrane switch
The buttons of the non-tactile membrane switch are not embossed or printed only with ink on the button frame. The realization of the function lies in the combination of the power-on point on the panel or the power-on point of the upper circuit and the power-on point of the lower circuit to form a line conduction. The main difference from the tactile membrane switch is that when the button of the graphic overlay is pressed, there will be no obvious sound and no tactile feedback is provided. The main way to judge the realization of the function is whether there is an optical change in the LED or LCD window. You can also use LED backlight technology to determine whether the function is realized by judging whether the button or font is lit.
Working Principle of flat membrane switch
The basic working principle of the membrane switch is as follows:
When the membrane panel is not pressed, the membrane switch is in a normal state, with its upper and lower contacts in a disconnected state, and the isolation layer isolates the upper and lower circuits; when the panel is pressed, the contacts of the upper circuit deform downward, It coincides with the lower line and makes the line conductive.
The conductive line sends a signal to the external connection instrument (substrate) to realize its corresponding function; when the finger is released, the upper circuit contact rebounds back and the circuit is disconnected. The loop triggers a signal.

waterproof membrane switch factory construction
Membrane switches are two main structures
The switch button is slightly raised, slightly higher than the panel, forming a 3D membrane switch. The convex is helpful to stimulate the operator’s sensitive touch, to help the operator accurately determine the position of the button, and to improve the recognition speed. The convex membrane switch can be designed into a variety, improving the decorative effect of the product and achieving a perfect appearance.
A flat structure was common in the initial stage of the membrane switch. The buttons on the membrane switch simply use color to express position, shape, and size. The accuracy of the operation can only be identified by the operator’s vision, and there is no appropriate feedback information to indicate whether the fingers press the effective range of the switch to make it work, thus affecting the confidence of the whole machine monitoring and control, and the speed of operation as well.

waterproof membrane switch supplier Materials Selection PC/PET
Membrane Switch and Tacitle Panel
Membrane panel is a type of HMI, in which the structure is generally PET, PC as the base material, DT, Nitto, or 3M as the adhesive material to assemble them. A membrane switch and panel is a kind of HMI with more prominent performance and lower prices.
The membrane touch panel is the operating system on many electronic controllers, medical accessories, and agricultural products, and it is also the first interface. Color matching and design are particularly important. Fortunately, as one of the most professional membrane switch manufacturers, Shanyo’s engineers and designers are very good at this type of membrane control panel. At the same time, we will strictly review whether the customer’s drawings and ideas can be realized.
Membrane Keyboard Switch Materials Selection PC/PET
1. Panel material:
Generally divided into two categories: PC (Polycarbonate) and PET (Polyester).
PC (Polycarbonate)
- There are bright and matte surfaces (fine sand, medium sand, coarse sand)
- Commonly used thicknesses are 0.125, 0.175, 0.25mm
- Special treatment includes HP series (such as HP40, HP60 and HP92S, etc.)
- Advantages of PC material: good ink adhesion.
- Disadvantages of PC material: poor corrosion resistance, difficult to use in outdoor products.
- Generally, those with Windows use a glossy PC, and those without Window use a matte PC. Matte PC is scratch-resistant.
PET（Polyester
Matte:
Autotype (thickness 0.15mm and 0.20mm) Kimoto (thickness 0.125mm and 0.188mm)
Bright side:
Autotype (thickness is 0.18mm and 0.25mm) Izaya (thickness is 0.125mm and 0.188mm) The above PET is treated PET.
Line materials:
PET has good insulation and heat resistance, high mechanical strength, transparency, especially bending resistance, and high elasticity. Therefore, PET is an ideal material for making membrane switch circuits.
- Generally, untreated PET is used;
- Thickness is 0.075, 0.1, 0.125mm.
- It is generally appropriate to choose 0.125mm. If it is too thick, the response will be slow and the switch sensitivity will be poor. If it is too thin, it will have insufficient elasticity and will not be conducive to the plug-in of the lead wire end.
Key piece (isolation layer) material:
Generally 0.1, 0.15, 0.20, and 0.25mm thick double-sided tape.
The thickness of the key sheet depends on the size and shape of the key, which is directly related to the operating pressure of the membrane switch and the sensitivity and reliability of the switch. Therefore, the size of the keyhole should be consistent with the size of the key pattern. When the size of the keyhole is larger, the thickness of the keysheet will also increase.
Membrane Push Button Switches Material Used In The Circuit Layer
Membrane Key Switch Material Used In The Circuit Layer
The base material of the circuit should be polyester(polyethylene phthalate) Film (Polyester referred to as PET).
It has good insulation and heat resistance, high mechanical strength, transparency, and airtightness, especially folding resistance and high elasticity.
Membrane Switch China Thickness of The Plastic
The thickness of the plastic substrate is 0.25mm or below and is called a membrane. It is mainly used as the panel layer of the membrane switch. Various indicative patterns and text are printed on the back to indicate the operation area of the corresponding key switch. Depending on the size of the button, the material is thick, the touch force is increased, and the response is slow; the material is too thin, the feel is poor when touched, and the rebound is not obvious. Thickness above 0.25mm is called a plate, which is not suitable for three-dimensional key forming. It can be used as an indicative sign panel in the keyless operation area, and can also be used as a lining for membrane switches to increase its hardness.
Custom Membrane Switch Circuit Ventilation Slot
The ventilation slot is generally 2mm wide, and there are no less than 3 keyholes connected to the ventilation slots, and 4-6 key connections provide better results. If the number of keys is less than 3, the key ventilation slot must be ventilated to the outside. It is ventilated to the outside and the buttons feel good to the touch.
Carbon paste is a non-metallic conductor paste that does not combine with oxygen in the air and can protect the underlying silver paste from oxidation. Carbon also has high wear resistance, which is convenient for plugging and unplugging leads and connection terminals.
Wholesale Membrane Switch Company Inks
It is divided into conductive ink, insulating ink, matte ink, and color ink.
- Conductive ink: silver paste, carbon paste, and silver-carbon mixed paste ;
- Insulating ink: plays an insulating role and is generally used for jumper insulation and entire surface insulation;
- Matting ink: window matting, panel matting;
- Colored ink: Due to different materials, the inks used are also different, including inks for PC materials and inks for PET materials.
Membrane Switch Dome Type
Shanyo can provide various types of custom membrane switches embossed keys, as shown in the picture below.
The default is circular relief (1st from left). If you need other types, please indicate it in the remarks or drawings when custom.
Membrane Switch with Metal Dome Key
This type of membrane switch uses a metal dome as the upper circuit layer of the switch. By pressing the key, the metal dome central point will connect the lower circuit, and then trigger with a signal. Metal dome is usually made of stainless steel, which is flexible and can be pressed more than one million times.
The keys of the metal shrapnel have a good button tactile and provide good tactile feedback to the operator. Shanyo uses a stainless steel cross dome and is available in specifications of 8.4mm, 10mm, 12mm, 14mm, and 16mm. The metal dome size of 10mm – 12mm is generally recommended, which is more suitable for the actual finger press.
