Manual Change-over Switches

_GENERALITIES
Manually Operated Changeover Switches, suitable for
breaking and switching between two low voltage electrical
circuits.
They are made by two standard switches of
VISUALCOMPACT series. mechanically interlocked.
The arrangement of two switches mounted one on top of
the other makes this execution particularly compact and
easy to connect to cables or bus- bars
