ABSTRACT:
A universal remote control mechanism for controlling a power spraying device comprises an electronic control contained within the nozzle housing of the sprayer. Membrane switches in the controller are actuated to cause radio wave signals to be generated and transmitted by an internal antenna. The radio signals are detected by a receiver which converts the radio signals into control signals for a main pumping unit. The radio waves may also control the introduction of various chemicals into the liquid solution by the main pumping unit. The nozzle also contains a deadman's switch for turning off the flow of liquid in case the unit is accidentally dropped. A delay feature lets the operator change hands without deactuating the system. The nozzle gun can be used for wired cable systems as well as for radio controlled systems.
