120VAC Lamp Dimmer

HOME
Manufacturer did not bother to design in the usual choke.

This must generate an awfull lot of RFI without a choke! The house wiring supplies the di/dt limiting. This is a CHEAP design which exhibits hysterisys at dim settings. Not everything made and sold to the public is top notch.
