Patchbays
Featuring the New Professional Punchdown Terminal
Our Patchbays Have Just Rounded A New Corner
Actually, the corners we rounded belong to our
patchbays’ revolutionary, new Professional
Punchdown Terminal (PPT), making it perfectly
compatible with the industry standard. We real-ized
that achieving a new industry standard
meant we couldn’t cut any corners to get
there.
The PPT design incorporates a split-barrel
design and a more rugged, thicker housing to
minimize the impact of repeated punchdowns.
The split-barrel design eliminates the problems
associated with the old “V-shaped” terminal
designs. The PPT design distributes pressure
evenly across both sides of the terminated
wire, causing improved wire retention plus
more reliable connections. The serrated teeth
in the plastic housing firmly grip the wires,
which also greatly improves wire retention.
With the PPT, multiple wires can be terminated
to a single contact, and a wide range of wire
gauges can be used.
Look for Switchcraft’s PPT in our APP and
Front Access Series of audio patchbays, and in
our new Backpanel Series. All Switchcraft au-dio
patchbays incorporate heavy gauge materi-als
and our high quality, nickel-plated, steel
framed jacks. Gold-plated, crossbar contacts
come standard!
