Abstract
Abstract A handle for a vacuum hose of a central vacuum system. There is a body having a first and second end. A nozzle projects outwardly at the first end and there is a recess at the second end to receive the vacuum hose. A pathway through the body joins the recess and the nozzle. There is a handgrip formed on the handle and a first connector means on the body, generally adjacent the first end. There is a switch adjacent the handgrip. Conductors join the first connector to the switch. A second connector on the body is generally adjacent the second end, and conductors join the switch to the second connection means.
