A Membrane Keypad / Keyboard usually forms a functional and aesthetic user interface between the control systems hardware and its software.
The basic principle is that a contact behind the tactile key or non-tactile key closes an open loop in the flexible circuit which terminates on the flexible tail (FPC). They have been used in domestic and industrial applications since the early eighties. In such time, advancements in materials and processes have enabled customers to benefit from an infinite number of Membrane Switches, Keypads / Keyboard design styles and applications and also reducing the set-up costs.
Customark is leading the way with advanced key backlit keypads and capacitive touch fascias. Our pro-active approach allows all our customers to benefit from our advancements in technology and processing techniques.
Membrane Keypads, Keyboards and Switches are a key part of any control system as they are both functional and informative. The graphic overlay on the front of the Membrane Keypad is the first item that an operator’s eye is drawn to. Consequently, the overlay has big influence on the user’s first impression. The feel of the Membrane Keypad is equally as important. The tactile feedback can be engineered as such to give the desired audible and physical click. Attention to detail, intelligent circuit design, precise colour matching and intuitive graphics and critical factors in creating an effective Membrane Keypad.
At Customark we have invested a considerable amount of capital expenditure in state-of-the-art finishing equipment which can offer enhanced production efficiently and where possible zero tooling costs.
Our experience and expertise in the technical graphics design, engineering and manufacturing of custom Membrane Keypads and Switches allow us to ask the right questions upfront to encourage and aid out the design for manufacture philosophy.
Our Membrane Keypads are used throughout many different industries which include electronics, white goods, medical, security and marine. The two main materials that are used in the production of Membrane Keypads, Keyboards and Switches are polycarbonate and polyester. We have direct supply and support from companies such as Sabic and 3M.
Polycarbonate (also known as Lexan) is not hard to process, ink keying, die-cutting and forming are very easy with this malleable material. Generally, if the Membrane Keypad / Keyboard is mostly aesthetic then this is the correct choice as it is less costly than PET. If the Membrane is going to be in contact with solvent-based chemicals or has high use keys, then this probably will not be suitable.
Polyester (PET) is a higher-grade material and available with more surface finishes and effect. Nearly always used when the Membrane Keypad / Keyboard is more functional. For example, if the Membrane Keypad / Keyboard has raised keys or push-button areas or the Membrane is to have a display. This material can also be laser cut which virtually eliminates the need for tooling, heat stabilised polyester is always used for the circuit layers as it produces a low resistance perfectly stable keypad circuit.
Membrane Keypad Features and Benefits:
- Tactile or non-tactile feel
- Integrated LED’s and fibre optic backlit keypads
- Adaptable design, totally bespoke to customers Membrane Keypad / Keyboard requirements
- Sub-surface graphics – Printing is done on the underside of the Membrane Keypad so it doesn’t degrade its graphics identity and won’t wear from use or cleaning
- Short lead times – approximately 2-3 weeks after artwork approval
- Adhesive selected to suit Membrane Keypad / Keyboard mounting application
Customark can also offer a prototyping service if you are just starting out with Membrane Keypads. This way you can get a feel for how your Membrane Keypads. This way you can get a feel for how your Membrane products are going to work before you commit to full production volumes. Always produced to our consistent high ISO9001:2015 approved quality.
