VARIOUS DESIGNS AND MATERIALS
INTEGRATION AS SYSTEM SOLUTION
LIGHTING TECHNOLOGY
According to customer requirements,
Schurter also
offers complete function units. The switches or keypads
are individually installed in the specific front panel.
Schurter additionally offers completely assembled
system solutions for integration of further components
and electronic modules. An example is the desktop
version for Metallic Panel keypads: the input system is
installed in a desktop housing with integral trackball for
mouse control.
Point illumination
Schurter offers the standard colours red, green, yellow,
blue as well as bi-coloured red/green for the point
illumination of the switches. Point illuminations in other
colours are available on request.

For applications in cold climatic environments,
the
Metallic Panel keypads can be additionally provided
with a heating overlay. For this reason, the keypad is still
pleasant to use even at frosty temperatures and the
freezing of the switches is prevented.

DATA SHEETS
Either a single-colour LED (2 pins) or a 2-colour LED (3 pins) is used to illuminate the switches.
If a single-colour LED is used, cable No. 2 is omitted.
Colour switching is possible using appropriate triggering.
Ring illumination
This design is homogeneous and available in red,
green, yellow, blue and bi-coloured red/green as
standard colours. Ring illuminations in other colours are
also possible.
