Abstract
A sprinkler controller includes a station timing dial having a front and back plate with an intermediate plate positioned therebetween. A plurality of switch plates having a tripper arm attached thereto are positioned around the periphery of the dial with each switch plate positioned between the front and back plates. Adjacent switch plates are positioned on opposite sides of the intermediate plates for movement circumferentially about the dial. The switch plates move such that one plate overlies an adjacent plate, thereby permitting the reduction in size of the station timing dial. The controller includes a clock and calendar dial using a plurality of sliders having a toggle portion and a cam portion. The toggle portion and cam portion are connected by a flexible arm which permits the movement of the toggle portion toward the cam portion to facilitate sliding of the slider switches relative to the clock and calendar dials. The sliders engage control switches for operating the controller. The controller permits the dual programming of certain stations permitting certain predetermined stations to be controlled in accordance with an alternate water program.
