With a rotating operation, pressure sequence switch, and gentle snapping, this device offers phase control. It utilizes a 2-wire connection technology, eliminating the need for a neutral conductor. Optimized for dimming Philips retrofit LED lamps, it is also compatible with incandescent bulbs, 230V halogen bulbs, low-voltage halogen lamps with conventional or electronic transformers, as well as dimmable halogen energy-saving lamps. Mixed operation with LED and traditional lamps is possible. The device operates quietly due to the use of MOSFET transistors and is short-circuit proof and overload protected with an electronic fuse. It features an adjustable minimum brightness and does not have a central disc.
