3. Film inserts
Instead of using engraving the lenses can be
fitted with transparent film inserts, as an
alternative. For this purpose, though, it is
advisible to use transparent lenses.
In the case of use of a smoke-black lens the
fitted film becomes readable only if the lamp is
on.
The film thickness is 0.2 mm.
Important : Consider pushbutton mounting
orientation befor specifying engraving
characters !
