Description
General notes
The series 18 comprises compact indicators for direct connection to
2.2, 12 or 24 VDC and illuminated pushbuttons with maintained or
momentary action.
The illuminated pushbutons are equipped with a snap-action switching
system with normally open or normally closed contacts.
The dimensions of the front are 9 x 14 mm, 9 x 9 mm or 9 mm dia.
Indicators and illuminated pushbuttons for use with overhanging lenses
14 x 14 mm or 14 mm dia. are also available for flush mounting.
Mounting
Mounting from the front through the mounting hole 8 mm dia.
(15.8 x 15.8 mm resp. 16 mm dia. for flush mounting) is assured even
with the wiring already attached.
The units are provided with soldering terminals.
Lenses
The flat lenses are available in various colours and a transparent
version. The surface is nonreflecting (matt).
Illumination
Perfect illumination of the lenses, which can be supplied in various
colours, is assured by Bi-Pin T1 LEDs (2.2 VDC) in the colours red,
yellow and green.
(Compact indicators for connection to 12 or 24 VDC.) The Bi-Pin T1
LED are already integrated in the lenses.
Luminosity and wave length scattering caused by the technology used
in the LED manufacturing processes may lead to visual differences in
our products.
Position indication
The status of a maintained action switch can be determinded by the
position of the lens.
