Abstract : The patent describes a phase controlled switch which connects a load to an A.C. power source at a particular phase angle of the power source. A first trigger signal referenced to a zero crossing region of the wave form is obtained. This first signal starts a timer which in turn generates a second signal. The variable timer can be preset to produce a delayed signal over a full period of the A.C. wave form. A latching switch system responsive to the timing signal connects the load to the power supply and holds the load connected until the power supply is physically disconnected from the load.
