ABSTRACT:
A switching circuit for controlling the selective electrical energization of a resistive or inductive load by an AC power source such that a switching operation is performed only when the current from the AC power source is nearly zero. Pulses synchronous with the zero crossings of the AC power source are used to trigger one-shots to effectuate appropriately gated delay pulses when the switching circuit is ON and OFF, respectively. A latching circuit connected to an ON-OFF switch activates and deactivates the switching circuit.
