Abstract
An electromechanical irrigation controller for use with a plurality of electrically activated valves for automatically regulating time, location, and duration of irrigation. A microcomputer provides a switching means for sequentially activating the valves and determines the dwell time on each valve. The microcomputer is activated by a clock mechanism having hour and day wheels with selector pins for determining the desired times and days of operation. A single activating switch is mechanically connected to the hour and day wheels by levers which are pushed by the selector pins. When a combined hour and day selection occurs, the levers push the activating switch to start the microcomputer. The frame for the controller is designed to minimize the number of parts, skill, and time required for construction. The hour wheel mounting includes a portion for retaining the hour trip lever. The day trip lever and an actuator link between the hour and day levers are held in position by a combination of integrally molded retainers and slots. The activating switch has a preformed hole in one corner which slips over an integrally molded stud and is then rotated under a bracket to a detent which holds the switch in position without further assembly.
