With control inputs for light switches and light buttons. Without a neutral connection, allowing for installation directly behind the light button or switch, even if no neutral wire is available. To protect the lamp, the switching occurs at zero crossing with soft on and soft off. In addition to the minimum brightness, the dimming speed can also be adjusted, which simultaneously changes the duration of the soft on and soft off. In the snooze function, the set value is dimmed down to the minimum brightness and then turned off, while in the children's room function, there is a gradual brightening up to the set brightness level. Short control commands turn the light on or off, while continuous controls adjust the brightness up to the maximum value. Suitable for resistive, inductive, and electronic loads.
