Equipment and devices installed in the outside or in contact with public, often require particularly rugged keyboards in the part exposed to users.
The front part and the keys are made of aluminum, steel or Teflon.
Often the graphics are applied over the metal parts so they can be replaced if damaged.
The type of contact normally used is the steel dome. To protect any display a tempered or shatterproof glass is used. Poptar produces anti-vandalic keyboards for a wide range: petrol stations, automatic gates, points of information, equipment for waste collection.
