Industrial machinery and equipment usually require strong and durable membrane keys switch，And can be used in harsh environments and extreme temperatures.These customized industrial operating interfaces require particularly excellent tactile sensing，At the same time, the environment needs to be sealed and waterproof, anti-fouling and the ability to withstand abuse.For industrial controls, we usually recommend the use of environmentally-friendly the Material of TPU overlay for industrial-grade membrane switch , because of their reliability, high touch and the ability to seal circuits and electronic devices behind them.
FERLO TECH specializing in customized human-machine control interface, Industrial electronic machines and equipment need to be protected from various environmental influences under special circumstances, such as ultraviolet radiation, humidity, high temperature, chemical corrosion, etc.，We have established an industrial-grade component mechanism on the customization of membrane switches，It is a multilayer structure (planar) type (non-locking) key switch composed of a certain elastic insulating material layer, which integrates functions such as keys, indicating elements, and instrument panels. The action of the membrane switch is only realized by the vertical movement of the elastic membrane. Although the elastic membrane has undergone millions of peristaltic movements, and the amplitude of the peristaltic movement is very small, only 0.1-0.3MM, and the material selection is reasonable, so the membrane overlay material It can withstand a long time of more than one million times without deformation, which determines the durability of the membrane switch.
With our design and manufacturing capabilities, we can provide customers with customized tactile membrane switch to meet custmer needs as user interfaces and key overlay. So as to meet specific customer requirements in terms of performance, visual touch and aesthetics.

Custom environmentally friendly TPU or PET material for Industrial grade of membrane switches
TPU(Thermoplastic polyurethanes ) is a kind of thermoplastic elastic material, which has certain hardness at room temperature, but can be softened and reshaped after heating.。 Because TPU has excellent wear resistance, toughness, weather resistance, grease and solvent resistance, in addition to high elasticity, high tensile strength and high ductility, TPU also has cushioning properties that can extend the service life of the membrane switch.
TPU material keys have excellent tactility and high reliability in harsh environments, and provide the following functions:
- TPUCan be made into any shape, size or color.
- Custom-designed actuators and flexible walls for optimal performance and touch feel.
- FPC(Copper material or silver) or carbon ink printing
- TPU key button connector options
- TPU key button backlight
- Laser etched backlight
- PU coating
- Parylene coating
- Anti-UV coating
- Conductive spacer
