Membrane switch adopts transparent/semi-transparent area (e.g. PVC, PET material) combined with key area, customized translucent window through UV screen printing process, supporting real-time display of device status or backlight indication; key surface can be combined with bulging design (raised height 0.3-1.2mm), to enhance the tactile feedback and pressing. The surface of the buttons can be combined with a bulge design (bump height 0.3-1.2mm) to enhance tactile feedback and press accuracy.
The conductive layer is formed by silver paste or carbon ink printing, the upper and lower circuit contact on-resistance ≤ 100Ω, trigger signal response. The window edges are ultrasonically welded or sealed with IP67 grade sealant to prevent liquid infiltration and prolong service life (press life ≥100,000 times).
Feature of Touch Screen LED Membrane Switches
The Window Membrane Switches adopts silk screen technology, which can produce various exquisite patterns and texts to meet the aesthetic needs of different users. Meanwhile, the panel design is flexible and diverse, allowing for personalized customization based on actual application scenarios.
The structural design gives it good sealing performance, which can prevent external factors such as dust and moisture from entering, ensuring the electrical performance and stability of the switch.
The circuit of the membrane switch can be printed with conductive materials such as carbon paste, silver paste, copper platinum, etc. The conductive layer can be folded freely, and the resistance can be controlled within the desired range.
The sealed structure makes it waterproof, dustproof, and oil proof, which can maintain normal operation in harsh environments such as humidity, dust, or oil stains, improving the reliability and service life of the equipment.
When designing, the issue of preventing electrostatic interference was taken into consideration. By using special materials and processes, it has good anti-static performance, which helps to protect electronic devices from the influence of electrostatic interference and improve the stability and reliability of the equipment.
The materials used have good insulation, heat resistance, bending resistance, and high resilience. Therefore, the service life of membrane switches can generally reach more than three years, or even longer.
Window Button Membrane Switches Applications
Home appliance control panels
Microwave ovens, washing machines and other equipment through the translucent window to display the operating mode, combined with backlighting to achieve night operation guidance;
Drum-packed button design optimizes the feel of pressing (operating force 0.5-1.5N) and reduces the probability of mis-touching.
Industrial Instrument Interface
Oil-resistant PVC window switches for machine tool consoles, resistant to cutting fluid erosion;
Emergency stop key adopts red light-transmitting window + double-layer shrapnel structure to enhance the level of false-touch protection (false trigger rate <0.005%)
