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.
What Is A Membrane Switch?
Membrane switches are generally made from five different layers. This includes membrane, graphic, tactile, rigid and static layers. The first layer contains the graphic interface for the user to control the machine. It can also include a flexible circuit for less expensive alternatives. Another layer will contain the printed circuit which allows a signal to be transmitted. The ink that is used for the printing on the circuit is generally made up of avariety of metals. This helps for the signal to be conductive for turning on and off. Membrane switches allow for communication to take place in electronic devices. Membrane switches are a piece of equipment that can be highly sophisticated or rather simple by design.
