Description
General notes
The series contains indicators and illuminated pushbuttons with
maintained and momentary action and one contact which may be
normally closed or normally open (snap-action element for closing). The
illuminated pushbuttons are fitted with snap-action or low-level
switching systems.
The front dimensions are 9 x 9 mm or 9 mm dia.
Mounting
Mounting from the front through the mounting hole is assured even
when the wiring has already been attached.
The units are equipped with soldering/plug-in terminals.
Lenses
The flat lenses, made of polycarbonate, are obtainable in various
colours. The transparent lens is available with translucent or
transparent support.
Marking
A limited amount of marking can be provided.
Illumination
Perfect illumination of the different coloured lenses is assured by
filament lamps Bi-Pin T1 longlife (6 ... 24 V) or LED Bi-Pin T1. LED are
available in the colours white, red, yellow, orange and green.
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.

Application guidelines

04.2009
When switching inductive loads such as relays, DC motors, and DC soleno ids, it is always important
to absorb surges (e.g. with a diode) to protect the contacts. When these inductive loads are switched
off, a counter emf can severely damage switch contacts and greatly shorten lifetime.
Fig. 1 shows an inductive load with a free-wheeling diode connected in parallel. This free-wheeling
diode provides a path for the inductor current to flow when the current is interrupted by the switch.
Without this free-wheeling diode, the voltage across the coil will be limited only by dielectric break-
down voltages of the circuit or parasitic elements of the coil. This voltage can be kilovolts in amplitude
even when nominal circuit voltages are low (e.g. 12 VDC) see Fig. 2.
The free-wheeling diode should be chosen so that the reverse breakdown voltage is greater than the
voltage driving the inductive load. The DC blocking voltage (VR) of the free-wheeling diode can be
found in the datasheet of a diode. The forward current should be equal or greater than the maximum
current flowing through the load.
To get an efficient protection, the free-wheeling diode must be connected as close as possible
to the inductive load!
