30 Year Industry Experience


HMI Solutions

Airlines are constantly challenged to enhance the passenger experience through technology, especially in seat controls, signage and ambience. TT Electronics aircraft interior solutions are driven by light-guide technology providing high impact cabin interfaces and illumination, combining capacitive touch, secret-until-lit and mood lighting solutions.

For over 30 years aircraft interior partners have trusted TT. Since we provided passenger control units (PCUs) for the world’s first lie-flat beds that debuted in the 1990s we have worked with our aircraft interior partners to develop innovative and sustainable solutions. Our designs and certified products are currently flying with the world's major airlines cabins, including business and first class.

Our in-house design and engineering team can work with you to develop innovative and functional designs. Fully managed from concept to delivery.

Passenger Control Units (PCUs)

Passenger control units (PCUs) are designed to the customer’s requirement using proven interface solutions including traditional membrane keypads, PCAP and touchscreen panels, capacitive switching and our patented backlighting technology which is lightweight and space-saving making it ideal for control panel applications on aircraft.


Cabin Signage

Return to Seat (RTS), Attendant Call Button (ACB), Illuminated Seat Indicators

We design and manufacture a range of cabin signage solutions incorporating simple white-only LED lighting to advanced colour shifting technology, enhancing the passenger experience and providing energy efficient solutions for the aircraft.

High quality signage using our patented low-profile thin-film backlighting technology deliver clear information to passengers and crew. LED indicators or information signs inform passengers and flight attendants to return to their seats, fasten their seat belts or advise ‘lavatory occupied’ for example. We manufacture information panels with additional features for specific areas of the aircraft including lavatories and galley ways.

Mood and Ambient Lighting

SIP Panels, Accent Lights, Flexible and Rigid Mood lights, Stowage Lights, Galley Lights, Fridge Lights, Mirror Lights and Logo Lighting. 

Designed to create an enhanced passenger ambience and in-flight experience, LED based mood lighting is a fundamental design element that can be personalized through colour, intensity, zoning and transitions.

Our lightweight and highly flexible mood lighting solutions incorporate single colour and RGB mood lighting for aircraft cabins and communications with the ECU controlled with a variety of interfaces.

Galley Equipment Interfaces

We provide enhanced control panel and illumination solutions for aircraft galleys.

Our thin film backlighting and capacitive switching technologies deliver simple, clean and functional designs for galley and business class bar areas including refreshment makers, bar counters and cocktail tables.


Flexible Light Strip

Flexible LED lighting strips provide a power efficient, robust and certifiable solution in white or RGB multi-coloured options that bend around a 75mm radius. The perfect blend of form and function for aircraft interior mood lighting and signage solutions.

Single colour or RGB-W, Complex curves achieved by tooling arc shaped strips, Weight and power saving, Low maintenance, Minimum bend radius 50mm, Tested for fire (smoke density and toxicity), temperature and ESD immunity, Interface RS485 – CanBus.

Control Panel Assembly

Our in-house design and engineering team can work with you to develop innovative and functional designs. We provide manufacturing solutions including PCBA, integration and assembly full build. Fully managed from concept to delivery, we provide full certification and qualification testing.
