Specialist Membrane Switch Manufacturer
Touch Panel Products have been manufacturing in Bristol for almost 50 years. We are a market leader in the design and manufacture of bespoke membrane switch products of all kinds, and supply to businesses all over the UK and beyond.
We provide membrane keypads, membrane keyboards, graphic overlays, fascia panels, membrane labels, digital print labels, nameplates, HSE signs, bespoke signs and flexible sensor tags.
Touch Panels offer a total service from initial concept through to prototypes and volume production. If you currently use membrane switch products or have a future requirement, call now to discuss your project.
Membrane keypads are very versatile electronic components. Constructed of one or more thin film membrane switches, they usually have a high quality, durable screen printed graphic overlay on top, providing resistance to a wide range of chemicals while also displaying custom graphics and text.
They are inherently sealed to IP54 standards due to the way they are constructed, providing a certain level of protection from dust and moisture ingress and making them rugged and long lasting. They are also easy to clean and are resistant to most chemicals and cleaning agents.
Multiple switches can be incorprated into a single unit, along with encapsulated components such as LED's or resistors, RFI/EMI shielding, or even EL backlighting. All of this contained within a product that is less than 1mm thick!

Membrane keyboards are typically larger and more complex versions of membrane keypads. They retain all the benefits of the smaller product but generally contain many more switches.
Switch connections typically exit on one or more flexible ribbon tails close to an edge of the keyboard. These tails can be terminated with different connectors, or the contact ends can be left open to mate with a ZIF connector.
A permanent 3M acrylic adhesive backing is applied to the keyboard to enable it to adhere to your product. While this adhesive will give a strong and secure bond to a majority of surfaces, we can provide higher specification adhesives for low energy surfaces if required.
At Touch Panels we design & manufacture to meet your exact specifications, so your membrane keyboard will always be just as required.
A graphic overlay is a high quality custom front panel, usually screen printed, suitable for display on the face of a product or case. Text and graphics are reverse printed onto a thin film polyester substrate, providing a wipe clean surface that is resistant to many chemicals and cleaning agents.
More complex features can also be printed, including coloured filter windows, surface varnish or lacquer, or selective texture. A permanent 3M acrylic adhesive backing is applied to the graphic overlay to enable it to adhere to your product.
Graphic overlays can be used as instructional labels, indicator panels with LED's or lamps illuminating from behind, or as a high quality, durable front panel to your short travel switches.
A fascia (or facia) panel is a custom graphic overlay which is adhered to a backing plate. The fascia panel is then supplied as a complete unit, ready to use in your product with no additional work required by the customer.
Backing plates can be made of various materials including aluminium and mild steel, with surface treatments such as anodising or powder coating. Moulded cases or even a printed circuit boards can also be used.
Touch Panels can provide the fascia panel using a backing plate from our range of approved third party suppliers, or we can adhere the graphic overlay to plates, cases or printed circuit boards supplied by our customers.
Using traditional screen print techniques, Touch Panels can provide high quality, custom membrane labels.
Text and graphics are reverse printed onto a thin film textured polyester substrate, providing a wipe clean surface that is resistant to many chemicals and cleaning agents. Printed details are then viewed through the material which protects them from accidental damage.
A permanent 3M acrylic adhesive backing is applied to the label to enable it to adhere to your product. While this adhesive will give a strong and secure bond to a majority of surfaces, we can provide higher specification adhesives for low energy surfaces if required.
Membrane labels are durable and high quality, for use in prominent areas where looks are important.
In addition to screen printed items, we can also provide custom digital print labels.
Text and graphics are surface printed onto very thin coloured polyester or vinyl film, using our Gerber Edge thermal printer. These films are available in a wide range of colours and finishes, including metallic and reflective. The label stock has a permanent adhesive backing which is suitable for most applications.
Printed details are fused with the surface of the material using heat and pressure and are scratch resistant, however we can apply a clear over laminate to provide additional protection if required.
Profiles are cut using our Gerber Envision plotter and can include complex shapes if required. Finished digital print labels are provided on a roll of silicone release paper for easy removal.
These digitally printed items are much cheaper to manufacture than similar screen printed items, and tend to be produced at a lower resolution. Digital print labels are ideal for simple, high volume items such as logo labels, machine serial number plates, part number labels, and many other products.
Touch Panels can provide you with a complete range of standard HSE signs and labels, with sizes to suit your particular requirement and safety need.
Produced using our Gerber Edge digital printer and incorporating industry approved colours, these signs can be of virtually any size. From a small self-adhesive label, to a larger panelised sign mounted onto a rigid backing material, Touch Panels can manufacture it all.
All signs are outdoor ready direct from the printer, with an expected life of between 3 and 5 years depending upon the exact materials and colours used. We can also provide a clear over laminate to extend the outdoor life up to 10 years and provide additional scratch resistance.
Signs can be customised for your exact requirements by changing text or graphics using our extensive library of symbols. We can even combine several different signs into a single product for convenience.
Using the same processes as HSE signs, Touch Panels can design and manufacture bespoke display signs for your specific needs, with custom text, logos and other enhancements.
Custom signs are not limited to only Health & Safety applications, we are happy to discuss signs of all types and for any situation. Indoor, outdoor, small, large, panellised, we can help whatever your requirements.
Our flexible sensor tags, sometimes called a security tag or asset tag, is a security device adhered to a product on display in a retail environment. The tag is designed to activate an associated alarm when tampered or removed, to alert the store to an attempted theft.
Our tags incorporate up to four layers of sub-surface screen printed circuitry, as well as custom surface logos and graphics in multiple colours. We manufacture both low and high resistance versions to work with different monitoring solutions.
Unlike traditional limpet sensors, our flexible sensor tags will adhere to virtually any surface, bend around corners, or even bridge across two separate components.
With clearly printed text and warnings, our flexible sensor tags can be used as a visual deterrent to potential thieves, as well as an effective electronic solution when connected to an alarm system.
