About Membrane Keypads
A membrane keypad consists of a printed overlay or fascia, typically made from polyester, and flexible circuit layers sandwiched together with spacer layers to make a complete switch assembly. The front overlay is custom designed and printed to a customers layout and can include a range of finish options. Numerous key structures are available to satisfy technical parameters such as tactile response, robustness and operational life.
The latest manufacturing techniques have increased the reliability of operation and membrane keypads are routinely used in rail, military, automotive, aerospace, security, control panels, and medical applications,
Compared with other interface solutions such as rubber keypads or capacitive touch technology, membrane keypads have the advantage of significantly lower cost tooling and simpler mechanical and electrical integration. For further details, visit our Membrane Keyboard Design & Construction page.
