Contact our HMI Solutions Team

Get the latest technology in capacitive touch screens, capacitive switch control panels and thin film backlighting, as well as transitional membrane keypads and control panel assemblies. 


We specialise in HMI solutions and technologies for major OEMs in the transportation, aircraft interiors, medical and heavy industrial sectors. As well as customised solutions, TT Electronics also offers a range of standard HMI products including single illuminated capacitive switches and push-to-exit panels. From design to manufacturing, we provide innovative product solutions and manufacturing excellence from ISO and SC21 accredited facilities.

Capacitive Switching 

Projected capacitive touchscreens do not rely on physical movement of the substrate to register a point of contact, allowing them to be bonded to the reverse of several different types and thicknesses of front cover material. These include glass, polyester, polycarbonate and others. This means assemblies can be made extremely robust, waterproof and vandal resistant. They have a high optical transparency, are easy to clean and have no moving parts. 

Multi-touch and gesture support are simple to implement and open up a range of possibilities for GUIs.

Capacitive Switching Features

  • Flexible
  • Up to 10mm thick
  • Glass, polycarbonate or acrylic
  • Fully sealed – suitable for harsh environments
  • Support of SPI, UART, RS232, I²C, and USB interface protocol
  • ATMEL components

Thin Film Backlighting

Using our patented thin film backlighting technology, TT Electronics can design and build bespoke illuminated control panels and display solutions. We can isolate illumination, giving an array of options to enhance or define products from flashing sequences to animated colour changes.

 

Applications for this innovative and customisable illumination system include backlighting of capacitive touch panels for HMI systems such as POS, ATM and industrial control panels, illuminated signage for indicators and instruction panels including secret-until-lit emergency signs for aircraft, point of sale and product branding.

 

Thin Film Backlighting Features

  • Low profile, typically 1.5mm
  • Low weight
  • High illumination uniformity – no hot spots
  • RGB LED’s provide comprehensive colour options
  • Secret-until-lit signs
  • High impact product branding
  • Low power consumption
  • Up to 13mm panel thickness (glass, acrylic or polycarbonate) for hostile environments
  • Suitable for consumer or industrial applications
  • Incorporating capacitive switches, slider controls, joysticks, tracker balls and displays

Custom Control Panels

We specialise in the design and build of fully integrated custom control panels to meet specific client or industry specifications.

Working with the design team at the beginning of the development process enables us to offer our knowledge and unparalleled experience to ensure the smartest and most appropriate HMI solution. We offer multi-discipline design and manufacturing expertise to provide customers with fully assembled and tested units – developing the complete solution, saving significant assembly time for the customer and reducing time to market.

Using the latest technologies including touch and thin film backlighting our bespoke solutions can help with Illumination hot spots, limited Z axis space, system integration, innovation and cost reduction.

 

Custom Control Panel Features

  • Complete HMI solution
  • Design support or designed to customer specification
  • PCB assembly
  • Integration and build
  • Choice of interface technologies including capacitive switching, touch screens, backlighting and traditional membranes.

Membrane Keypads

Custom design and print membrane keypads and overlays. Small volume can be produced in the UK with larger volumes available from our Asia manufacturing facility.

PCB-based membrane keypads, combining a membrane keypad with a double-sided or multilayer PCB, eliminate the need for a support panel. Stadium IGT provides a turnkey service to populate the switching PCB plus any additional daughter PCBs with electronic components from your bill of materials saving space, interconnection and final assembly time. We can provide integration into complex sub-assemblies or provide a fully assembled and tested unit.

We can also incorporate almost any interface technologies including capacitive glide pads, joysticks, tracker balls, touch pads, mechanical switches and touch screen solutions.

 

Graphic Overlays

Graphic overlays can be used to enhance a product or to provide an easy clean unbroken cover for mechanical switches and display. They produce an attractive finish and boost the all-important corporate image. Graphic overlays are used in all types of industries sectors and in a variety of equipment. TT Electronics uses a full range of materials, inks and adhesives to offer the best solution for different applications.

Materials include polyester (textured, gloss or chrome effect finish), PVC (textured or gloss finish), polycarbonate (textured or gloss finish) and stainless steel foil (brushed, etched and printed).

Key Features

  • Sealing up to IP65, IP67 or IP69K
  • Tactile or non-tactile key response
  • Dome, Pillow or Rim embossing
  • Chemical and UV resistant overlay materials
  • RFI / EMC / ESD protection
  • Surface mount LED’s 
  • Interchangeable legends or Inserts
  • Colour matching via photo spectrometer and VeriVide
We can also incorporate almost any interface technologies including capacitive glide pads, joysticks, tracker balls, touch pads, mechanical switches and touch screen solutions.

Single Illuminated Capacitive Switches

PCB-based membrane keypads, combining a membrane keypad with a double-sided or multilayer PCB, eliminate the need for a support panel. We provide a turnkey service to populate the switching PCB plus any additional daughter PCBs with electronic components from your bill of materials - saving space, interconnection and final assembly time. We can provide integration into complex sub-assemblies or provide a fully assembled and tested unit.
