ABSTRACT:
A timing device has a day dial and a time dial which rotate to control an electrical output in a programmed manner for a predetermined day period. The time dial and day dial operate a pivotally mounted lever to actuate a switch which is connected between electrical input and output, or load, connectors. The time dial operatively contacts one end of the lever and the day dial operatively contacts the other end of the lever when the dials have been preset to do so by the use of actuating pins which can be positioned in the dials. When both ends of the lever are contacted, the switch is actuated. The pins can be held in their respective time dial or day dial in an operative or inoperative position. Manual means are also provided to bypass the time dial and day dial by directly connecting the input connectors to the output, or load, connectors.
