PET Membrane Switch keypad with LEDs and FPC circuit for Ericsson products
Components of a Membrane Switch
Membrane switches are made up of two flexible printed circuits, physically separated by a spacer. When the button is pressed, holes in the spacer allow the two circuits to contact completing the circuit. The printed top layer is known as the Graphic Overlay. It is normally made of clear polycarbonate or polyester, and reverse printed to protect the image from wear, solvents and abrasion.
Membrane switches, when combined with components such as a tactile dome, graphic overlay, or integrated LEDs or resistors can provide the designer with virtually limitless capabilities to create the ideal custom user interface for their products.
Membrane switches are a thin durable form of momentary switching that is commonly used throughout industry. Membrane switch is made of several layers including soft insulating material and electric material, with free lock and touch feature. It is assembled with the function of switch, front panel, graphic overlays, LCD Transparent windows, imbedded LED, soft circuit panel, male connector and electroluminescent (EL) backlighting.
