The switch
testing device DIGISWITCH model 5410 was developed
especially for the testing of switches and buttons
acc. to DIN 41635 resp. DIN 41636.
With the simultaneous capture of force, displacement
and switch point, the complete switch characteristic
can be displayed and evaluated on the 120 x 88 [mm]
LCD.
With a sample rate of up to 5 work pieces per second
the device is well suitable for online testing in
production. Nevertheless, also in the laboratory or at
simpler manual work places the device can be of great
assistance for spot-checks.
Next to the PLC-output switches OK/NOK the various
measurement values as well as the complete measuring
curve can be transferred to a PC via the RS232
interface. Fast work piece changes with varying switch
characteristics are not a problem for DIGISWITCH. The
32 work piece related parameter sets can be selected
via PLC or the device’s menu.
Together with the PC software one can save even more
data sets. Furthermore, it serves to protocol the
measurement results, to up- and download the complete
device settings, etc.

The
complete switch characteristic is recorded and
evaluated with the help of specific attributes such as
switch point, reverse switch point, actuation movement
and difference movement.
Next to the mechanical values the electrical switch
point is also captured. In order to do so, a window is
set at the striking position. If the measuring values
lie beyond the preset limit value within this window,
the window is evaluated as NOK.
In an additional field on the LCD the evaluation of
every window is displayed next to the graphic. Only if
all preset limit values are in accordance, the switch
is evaluated as an OK part which is also transmitted
to the PLC with an OK signal. The capture of the
switch characteristics with evaluation is effected
optimally within 200 ms. In case of a defect on the
sensor the limit force switch-off is effected with a
reaction time of approx. 2 ms.
A complete switch test installation can be configured,
consisting of the DIGISWITCH model 5410 together with
the linear positioning actuator model 5490-Z001 and a
load cell.
