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