Standard membrane keyboards
As an established manufacturer of membrane keypads, we offer you a wide program of standard membrane keypads. These keyboards are available from stock, what allows a very quick and simple delivery, already for one piece only. The tool costs for standard membrane-keypads are also free, what allows a very good cost-performance ratio.
Pressure sensitive mat with pressure point, back side with adhesive layer.
Beside our standard membrane keypad program, the suitable pressure sensitive keypads are also separately on stock and available. Some of our standard membrane keyboards can be labeled individually with the help of insertable strips.
