ABSTRACT:
A control system for energizing and de-energizing external loads in series with a source of electricity incorporates a rectifying network having inputs in series with the alternating current source and each external load. The control system incorporates one electronic switch, such as a triac, and one part of a rectifying network to energize and de-energize each external load. The triggering of a particular electronic switch is made in response to a desired combination of externally sensed parameters obtaining predetermined magnitudes. The same or different sensed parameters may also be used to activate any other external load when these sensed parameters obtain a second set of predetermined magnitudes, which may be identical with the first set of predetermined magnitudes.
