Electrical dimmer system employing alternately applied silicon controlled rectifiers

A dimmer control system comprising, in combination:

• first and second conductors spaced apart from each other and respectively connected to the positive and negative terminals of an AC voltage source;
• a first silicon controlled rectifier discrete current switching device and a second silicon controlled rectifier discrete current switching device, each of said switching devices connect between said fist and second conductors such that said first discrete current switching device conducts current to a load during a portion of the half cycles when positive AC voltage is applied to said first conductor and said second discrete current switching device conductors current to said load during a portion of the half cycles where positive AC voltage is applied to said second conductor;
• first and second gate energization circuits respectively, connected to said first and second silicon controlled rectifiers;
• said first gate energization circuit comprises a first capacitor and a first diac connected in series with the gate terminal of said first silicon controlled rectifier and said second gate energization circuit comprises a second capacitor and a second diac connected in series with the gate terminal of said second silicon controlled rectifier.
