Membrane Keypads
We design durable, fully customised membrane keypads with abrasion-resistant printing. We are the only company in Poland to offer advanced LGF backlighting and dust-free lamination of touch panels using OCA technology.
Product description
Membrane (foil) keypads are a proven solution in consumer and industrial electronics wherever full design freedom, durability and resistance to harsh operating conditions matter. Thanks to a multi-layer construction of precisely selected technical films and an integrated electrical circuit, the panel becomes an integral, aesthetic part of your device's housing.
- Graphics that last for years - the graphics are printed on the inner side of the polyester or polycarbonate film. The print therefore has a physical protective barrier and does not wear off even under intensive, long-term use or frequent cleaning.
- Flexible construction and rich equipment - we integrate components inside the keypad matched to your device: SMD LEDs signalling operating status, metal snap domes (clicking) giving clear haptic feedback, silicone mats improving operating comfort, and replaceable legend inserts that make it easy to personalise devices in different language versions.
- Simple, stable integration - the integrated tail ribbon ensures trouble-free electrical connection to the device's main board.
Embossing types
The right embossing of the top film determines not only the look of the device but above all how comfortable it is to use. It gives the keys a distinct structure, makes eyes-free navigation easier and provides satisfying tactile feedback with every press. We select the embossing technology and profile to match how your device is used and what its users expect.
SMD LEDs
LED illumination can be used in every membrane keypad technology we offer. As standard we fit LEDs from Kingbright and Everlight.
Available colours: red, green, yellow, orange, white, blue, and bi-colour LEDs.
With SMD LEDs we recommend colour filters over the LED windows (matching the LED colours, or grey). This improves the keypad's appearance - the LED is not visible through the top film.
Developing and putting into production the mounting of SMD LEDs in the 0402 package (just 0.5 mm high!) significantly improved durability parameters and widened the use of LEDs as one of the ways of backlighting membrane keypads.
Keypad backlighting
There are several ways to backlight membrane keypads. Selective backlighting of areas of the keypad surface is possible (e.g. a company logo), backlighting of chosen pictograms only, of keys, of pictograms on keys and so on. Transparent windows can also be left in the keypad, to be lit by the device's own internal light.
Legend inserts
An interesting technical solution that lets a single keypad design serve different models (options) of the same device. Different key legends can be introduced (e.g. depending on the functions available in a given version). An insert can also carry information about the device's parameters, the manufacturer, etc. Using this technology does not compromise the sealing of the keypad (foil front).
Technical parameters
Exact technical parameters are confirmed after analysing your project's requirements
Tail terminations
We offer the following ways of terminating the tail ribbon.
Mounting instructions
Thoroughly degreasing the housing surface guarantees the best adhesion of the keypad to the substrate.
- Peel back a fragment (approx. 1 cm) of the protective silicone paper from the underside of the keypad.
- Position the keypad correctly and stick the peeled fragment to the substrate.
- Gently lift the unattached part of the keypad and remove the remaining silicone paper. Take care that, once the paper is removed, the tail ribbon does not stick to the exposed adhesive surface.
- Carefully pass the tail ribbon through the opening in the housing. Stick the keypad down so that no air remains between the keypad and the housing. Take care not to crease the tail where it exits.
Tearing the keypad off causes irreversible mechanical damage and makes it unfit for further use.
