... Power Blinking Switch 1. Description The integrated circuit, T2117, is designed as a zero-voltage switch in bipolar technol- ogy used to control resistive loads at mains by a triac in zero-crossing mode. A ramp generator allows power control function by period group control, whereas full-wave logic guarantees that full mains cycles are used for load switching. ...
