Specifications

Remote indication of the contact position can be
accomplished by means of the add-on auxiliary
contact module PLS 0411 (photo 2). The auxiliary
contact can only be mounted on the left side of the
device.
Independent of coil voltage or number of contacts,
always the same add-on module for centralised
command PLS C can be used (photo 3). The
centralised command module can only be mounted
on the right side of the device.
Additionally, the PLS M multi-level centralised
command module allows an almost unlimited number
of hierarchical levels for grouped on off switching.
Figure 8 shows the wiring for a multilevel centralised
command application.
Both an auxiliary contact module and a central
command module can be mounted on the same
device at the same time.
Electromechanical step-by-step
impulse switches
If two different circuits need to be operated with
only one pushbutton, possibly from different places,
step-by-step, multi-circuit impulse switches are the
solution. The subsequent contact positions are
shown in table 1.

Comfort Functions
Example: one hall with 3 rows of lights (see fig.9);
in step 1, no lights are activated, in step 2 only the
middle row is activated, in step 3 all rows are activated
and in step 4 both outermost rows are activated.
Assuming all lights have the same characteristics,
in this way the light-intensity can be regulated in
4 steps: Off, 33%, 66% and 100%.
