The TSL ESCHA presskeys of the series PK 21 have all
the time-tested properties of the PK 20 presskeys.
In addition, they offer a higher degree of operation convenience: For example, twelve LEDs serve for reset and switching indication.
As an optional extra, an acoustic acknowledgment is also possible.
In the choice of colours and pictograms we are only too pleased to satisfy your requirements.
