When expanding the number of switch buttons or the

prior configuration remains and must only be expanded.
In the same simple fashion switching between design
lines (DELTA line / vita / miro, DELTA profil oder DELTA

Configuration and operation of all instabus wall switches
is identical independent of design and the number of
switch buttons.

General description
The wall switch is slid onto the bus coupling unit (BTM)
together with its design frame (DELTA style).
Bus coupling unit (BTM) and the design frame “DELTA
style” are not included and therefore have to be ordered
separately (see current catalog).
Mounting
− Slip the wall switch's main module (F5) together with
the design frame (F3) onto the bus coupling unit (BTM)
(F1) and firmly press them together.
The electrical connection between the wall switch and
the bus coupling unit (BTM) is established via a Bus
