Marking
General notes
1. Engraving
In addition to the most commonly used world languages, in
DIN1451-3 close spacing, other typefaces are available as Scandi
-
navian, Slavic, Greek, Russian and Polish. Red, blue and black
lenses are lled with white colour. Other colour lenses arelled in
black. Standard height of letters is 2
mm. If the height is not speci-
ed, we will supply 2
mm engraved letters.
2. Hot stamping
For larger series it is worth considering markings by means of hot
stamping. We will pleased to advise you. For letters and gures,
typefaces with 2.5
mm, 3 mm and 4 mm are available.
3. Film inserts
Instead of using engraving the lenses can be tted with transparent
lm inserts, as an alternative. For this purpose, though, it is advis-
ible to use transparent lenses. In the case of use of a smoke-black
lens the tted lm becomes readable only if the lamp is on. The
lm thickness is 0.2 mm.
Important: Consider pushbutton mounting orientation befor specifying
engraving characters!
