Push button family PK21-29 with new surface coating
The Presskey push button has been a favorite for over 30 years. Even successful button families need an upgrade from time to time. Thanks to modern material formulations, the push buttons PK21-29 are now even more durable as standard.
The touch surface is given an additional surface protection by the application of a hard-coating, this process has been tried and tested for years. This protects the transparent parts made of polycarbonate against the increased environmental influences and cleaning processes. This added value is free of charge for our customers.
The well-known surface coating against graffiti-remover chemicals remains on offer as an additional option (subject to a charge). Again, the material has improved performance and a longer durability.
As a result of the measures implemented, the tried and tested TSL-ESCHA push buttons now even better meet the increased requirements of daily use.
