Numerous configurations
The five series offered by APEM not only meet the
needs for standard keypads and keyboards, but also the
needs for customised products with specific number of
keys and key layout. Depending on the series, standard
keys differ in shape and dimension; in all cases, custom
marking is available. The APEM range also includes
stainless steel keypads and keyboards with backlighting
by LED’s..
