Keypads, Keyboards & Switches are a key part of any Control System
- Membrane Switches
Membrane keypads, keyboards & 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 a Operator's eye is drawn to. Consequently, the overlay has a
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 are 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 efficiency and where possible zero tooling costs.
Our experience and expertise in the technical graphic design, engineering, and manufacturing
of custom membrane keypads & switches allows us to ask the right questions up front to encourage
and aid our design for manufacture philosophy.
Our membrane keypads, keyboards & switches are used throughout many different industries which include,
Electronics, White Goods, Medical, Security and Marine.
If you are looking for features that are specific to your product
we can design and manufacture membrane keypads / keyboards that include:
- Wide variety
of Polyester and Polycarbonate finishes
- Materials selected for environmental suitability
- Anti-microbial membrane finishes
- UV Stability
- IP65, IP67, IP68 rated
- Tactile or non-tactile feedback keys
- Rim, Pillow of Custom embossing keypads
- Braille Keypads
- Integrated LEDs
- RFI/ESD/EMC shielding
- Fibre Optic backlighting
- Interchangeability of key Legends
- Full turnkey production including sourcing of panels, Aluminium/steel
- High precision laser cut production virtually eliminating tooling
The two main materials that are used in the production of Membrane
Keypads, keyboards & Switches are Polycarbonate and Polyester. We have direct supply
and support from Companies such as Sabic and 3M allowing is to
develop products to exacting standards and supporting our commitments
to RoHS when producing our membrane keypads & switches.
Polycarbonate (also known as Lexan) Is very easy 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 slightly less costly
than PET. If the membrane is going to be in contact with
solvent based chemicals 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 has raised keys or push button areas or if the membrane
is to have a display. This material can also be laser cut which
virtually eliminates the need for tooling. Heat stabilized polyester
is always used for the circuit layers as it produces a low resistance
perfectly stable keypad circuit.
Membrane Keypad Features & Benefits
Membrane keypads, keyboards & switches are manufactured in an infinite number of shapes,
sizes and materials, but share these common features and benefits:
- Tactile or non tactile feel
- Integrated LED’s and fibre optic backlighting
- Adaptable design, Totally bespoke to Customers membrane keypad / keyboard requirements
- Sub-surface graphics – Printing is done on the under-side
of the membrane keypad so it doesn’t degrade its graphic
identity and won’t wear out from use or cleaning
- Short lead times – approximately 2-3 weeks after artwork
- 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 product is going to work before you commit to full production volumes. Always produced to our consitent high ISO approved quality.
