Berker 85421200 Modulo dimmer universale a sfioramento, 1 canale, da incasso, 230 V, 20-420 W/VA, compatibile LED

Unlike conventional rotary dimmers that demand a dedicated control dial, the Berker 85421200 Universal Push-Button Dimmer Module turns any standard push-button into a full-featured dimming control. This single-channel insert fits flush into standard wall boxes and handles a remarkably wide load spectrum—from classic incandescent and halogen lamps to modern dimmable LEDs and compact fluorescents—without swapping modules or adding extra interfaces.

Highlights

• Universal load compatibility: incandescent, HV halogen, LV halogen (inductive/electronic), dimmable CFLi, dimmable LED
• Push-button operation with memory function and soft start for gentle lamp ignition
• Adjustable minimum brightness to eliminate flicker and ensure stable low-level dimming
• Built-in short-circuit, overload, and thermal protection for long service life
• Extension inputs allow multiple push-buttons to control the same light from different locations
• Compact 32 mm installation depth fits standard flush-mounted boxes

In daily use

Installation is straightforward: wire the module behind a standard push-button, set the desired minimum brightness via the integrated potentiometer, and you're ready. A short press toggles the light on or off; a long press dims up or down. The memory function recalls the last brightness level when switched on, while soft start extends lamp life by ramping up voltage gradually. If you need control from two or more points, simply connect additional push-buttons to the extension input—no extra modules required.
