We are a Membrane Switches manufacturer engaged in Graphic Overlay,Membrane Panels, Soft Circuits, Silicone Rubber Keyboard, LED , LGF Silicone Rubber Keypad. All kinds of customization, welcome to come to consult.1. Panel layerThe panel layer is generally made of exquisite patterns and texts by silk-screening on PET, PC and other colorless light-transmitting sheets less than 0.25MM. Because the main function of the panel layer is to play the role of logo and buttons, the selected materials must have high transparency. , High ink adhesion, high elasticity, high toughness and other characteristics.2.The surface glue layerThe main function of the surface glue is to closely connect the panel layer and the circuit layer to achieve the effect of sealing and connection. This layer generally requires a thickness between 0.05---0.15MM, with high viscosity and anti-aging properties; in production , Generally use special Membrane Switch double-sided adhesive, some membrane switches are required to be waterproof and high temperature, so the surface adhesive uses different materials according to needs.3. The upper and lower layers of the control circuitThis layer uses polyester film (PET) with good performance as the carrier of the Switch circuit pattern, and uses a special process to Screen-print conductive silver paste and conductive carbon paste on it to make it conductive. Its thickness is generally 0.05-- Within 0.175MM, 0.125MM

Membrane Switch is an operating system that integrates key functions, indicating elements and instrument panels. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane Switch is pressed, the contacts of the upper circuit are deformed downward, and are in contact with the pole plate of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal. The membrane switch has strict structure, beautiful appearance and good sealing performance. It has the characteristics of moisture resistance and long service life. Widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, smart toys, household appliances and other fields.
Membrane switch, also known as light touch Keyboard, adopts an overall sealing structure composed of plane and multi-layer combination. New electronic components are a fundamental change in the appearance and structure of electronic products. They can replace the buttons of conventional discrete components and perform the tasks of the operating system more reliably.
Membrane switch has good waterproof, dust-proof, oil-proof, anti-harmful gas erosion, stable and reliable performance, light weight, small size, long life, convenient assembly and connection, the panel can be washed without the characters being damaged, the
