Outdoor Application Membrane Switches
An outdoor waterproof membrane switch assembly is an electronic input device specifically designed for outdoor environments, featuring waterproof, dustproof, and weather-resistant properties.
Through the use of special materials and structural design, it ensures reliable operation even under harsh outdoor conditions.
These assemblies are commonly used in outdoor devices requiring user input, such as vending machines, outdoor instrument panels, navigation systems, security equipment, and outdoor control panels.
Overlay
Material: Typically Autotex Xe series Polyester(PET) material, known for high wear resistance and UV resistance for out door application.
Design: The surface is printed with user interface icons, text, and symbols using UV-resistant ink to prevent fading under sunlight.
Sealing Layer: The sealing layer between the overlay and the circuit layer ensures the keypad area is waterproof and dustproof.
Spacer Layer
Function: Provides the necessary rebound force after keypress and prevents accidental contact between circuit layers.
oMaterial: Usually made of double-sided adhesive or other isolation materials with waterproof properties.
Bottom Circuit Layer
Material: Can be a rigid printed circuit board (PCB) or a flexible printed circuit (FPC), chosen based on application requirements.
Function: Offers more circuits and connection points for complex control functions.
Adhesive Layer
Function: Firmly attaches the membrane switch assembly to the surface of the equipment, ensuring long-term stability.
oMaterial: Typically uses high-adhesive double-sided tape with waterproof properties.
Seal Frame
Function: Provides additional sealing protection around the edges of the membrane switch to prevent moisture and dust ingress.
Material: Commonly made of silicone or other flexible waterproof materials.
