Description.

This is a modification of the circuitSimple Lamp Dimmer/Fan Regulator? previously? posted here. The working of the circuit is same as that of the previous, but in addition a snubber circuit consisting of resistor R4 and capacitor C3? is included to improve the performance of the triac T1. A fuse is also included for better safety. I think this is the better circuit to try .
