Change-over switches manually operated suitable for breaking and permutating two low voltage electrical circuits.
They are made by two standard switches of VISUALCOMPACT P 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.
