Abstract
A vacuum hose has a switch that allows an operator to selectively send control signals to a transceiver to control the operation of a central vacuum unit. The switch may be located on a cuff or nozzle defining a distal end of the vacuum hose. The switch is not located on a head unit that couples to the cuff or nozzle and not located on a wall-mounted valve. The switch can be an energy harvesting switch that requires no batteries or no dedicated power source (i.e., not hardwired).
