Abstract
An automatic reset timer includes two separate switches having operators held in timed out position by individual latches. A clutch is released by one operator when the timer is timed out. A solenoid also controls the latches for the two switches and also controls the clutch directly. A clutch mode selector is accessible outside the case and may be set for on delay, off delay, or neutral. In neutral the clutch is not controlled by the solenoid and is released only when the timer is timed out. Other mode selectors outside the enclosure control solenoid operation of the switches. They may be caused to transfer from timed out to timing position by either solenoid energization or deenergization. A third position provides for instantaneous operation of one switch by the solenoid. Selection of clutch and switch modes of operation makes a single unit field adjustable in many different combinations, simplifying application to a given problem and reducing models required to be stocked.
