Description
General notes
The series 31 illuminated pushbuttons are equipped with snap-action or
low-level switching elements.
Besides the standard contacts (gold-plated silver) silver contacts for
switching elements 2.8 mm plug-in terminals can be supplied on
request.
The front dimensions of these units are 18 x 24 mm, 18 x 18 mm or
18 mm dia.
In addition to a number of illuminated pushbuttons, the customer can
choose from a range of other units and accessories having the same
front and mounting dimensions: Indicators, Flashers, Buzzers, etc. (For
keylock switches see series 51 or 61.)
Mounting
All switch actuators are mounted from the front by pushing them through
the mounting hole in the front panel. They are then fixed from the back
with a fixing nut and the mounting tool Typ-Nr. 01-907. Max. tightening
torque 50 Ncm.
For switching elements with 2.8 mm plug-in terminals, we offer plug-in
bases, which when soldered to a PCB enable a plug-in connection to
the button. The rectangular actuators are provided with an anti-twisting
device.
Lenses
The flat or concave lenses, made of Polymethyl Methacrylate, are
available in various colours, as well as translucent or transparent.
Marking
For further information about engraving, hot stamping and film inserts
see part Marking.
Illumination
The T1
ensures perfect illumination of the lenses, which are supplied in various
colours.
T1
in blue, green, red, white or yellow.
Luminosity and wave length scattering caused by the technology used
in the LED manufacturing processes may lead to visual differences in
our products.
For supply voltages above 48 V, it is necessary to use a voltage
reduction element (external series resistor or transformer).
Position indication
The status of a maintained action switch can be determinded by the
position of the lens.
