Abstract
A rain activated control system which shuts off an irrigation pump when a predetermined amount of rainfall occurs. A receptacle for catching rain is mounted in a manner to provide adjustment of the distance between its bottom and a pair of electrodes which extend into the receptacle. When rain is collected in the receptacle in sufficient quantity to immerse the electrodes, a control circuit is completed to operate a relay. The energized relay then activates the shut down system of the engine or motor which drives the irrigation pump. Ater a time delay sufficient to assure complete shut down of the pump, a timing circuit causes deenergization of the relay and closes a reset circuit. When the irrigation pump is to be restarted, the rain receptacle is emptied and a reset switch is opened to reset the control circuitry.
