Vandalproof numeric block in high quality steel construction

The 4s numeric block is a button field with 4 buttons with from inside illuminated button symbols (different colours are possible). With a circuit board as a pure matrix-LP and as a mounting version in high quality steel construction. Our high quality steel keyboards are conceived explicitly for surroundings where there is danger by vandalism or you ask for high claimable for customer traffic and/or weather proof. Our high quality steel keyboards just come to the application in industrial extreme surroundings. Absolute dust- and spray waterproof as well as a very high degree of insensitiveness as compared with violence take care that our high quality steel keyboards can absolutely reliably carry out its job.
