This Ducted Vacuum Hose with switch has a switch on the handle which allows you to switch your ducted vacuum system on or off at any time without going to the inlet.

If you are upgrading from a standard hose to a switched hose please check all of your inlets, they must have two low voltage metal contact pins inside the hole of the valve. These pins are what make it possible to use a on your system, many older ducted vacuum inlets had a hidden micro switch attached to the flap or a single ball bearing switch, these inlet valves are not compatible with a switch hose, however you still upgrade to a switch hose if you replace all of your inlets to the modern 2 pin type ducted vacuum inlet valve.
