Red Green LED Tactile Membrane Switch Keypad, Switch Type Membrane FPC Circuit
LUNFENG membrane switches are produced to the highest standard by our skilled operators and in compliance with ISO 9001 Approval, which ensures your membranes are fully functional and to the highest standard. All membrane switches undergo 100% final test inspection to ensure error-free operation and that the buttons last as long as the machine they control.
An optional second circuit or PCB layer contains additional circuits required for membrane switching applications. This layer usually includes the bent cable or interface pins required for integrated thin-film switches.
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.
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.
