3M Adhesve PET Membrane Switch

PET Membrane Switch FPC circuit flexible circuit


When a company begins the process of bringing a product to market that contains an HMI (Human Machine Interface), membrane switches are one of the most common technologies selected because of their high reliability, relatively low cost, and level of customization.


Membrane switches are everywhere, just look around, but how many people truly pay attention to the circuit design? Typically, HMI engineers and designers focus on the visible design elements first, such as overlays, pantone colors, and backlighting. Next, the focus is usually on the keypad design, such as the switching mechanism, keypad material, and tactile response. Unfortunately, all too often, designers and engineers fail to provide sufficient attention to one of the most critical design features of a membrane switch, the flexible circuit behind the overlay.


Flexible Circuit Options

Flexible circuit options include polyester (PET) that uses silver ink as the circuit element, and flexible PCB (FPC) that uses copper as the conductive element. Form, fit, and function is very similar for both though their respective costs and reliability can drastically differ.
