"Bought one to test on a Biax metal scraper which has a single speed 220w AC brush motor. The scraper as standard only had one speed making it awkward to use, fitted this dimmer switch as an in line speed controller and now have a completely variable speed unit. Works great and at a fraction of the cost of a variAC."
"Within bocDy of description, states 1 Gang 250W for 1 / 2 Way Circuits. But only suits one way circuit (ok, the title says one way, but description implies otherwise. Go gor push dimmer if u need 2 way. Cheap price, average quality"
