Special place in our production takes the manufacturing of foil keypads and front panels for various electronic devices as vending machines, cash machines, alarm systems, etc. Important part of this production is the design and the precise performance of each article as we use high quality materials, foils, inks, buttons and keys, connectors, domes and light emitting diodes.
The products are as follows:
- Flexible
- On PCB or printed circuit board
- Tactile
- Sensor
- With EL (electroluminescent) backlightning
