DIMAX 540 Flush-Mount dimmer: Dimming with or without a neutral wire

Smart light control even where space is limited or there is no neutral wire? The DIMAX 540 mini dimmers offer the perfect solution and fit behind any standard switch. Ideal for retrofitting during renovations, but also practical in new construction!

Mini-dimmers for any flush-mounted box

The DIMAX mini dimmers are an excellent solution for reliable, space-saving, and smart light control. Variants without a neutral wire, with a neutral wire, with configuration via the app, or without an app offer a wide range of options for many applications. Measuring just 25.5 x 26.6 x 10.4 mm, the DIMAX 540 plus B flush-mounted mini-dimmer is barely larger than a 2-euro coin. The 4-way conductor versions and app versions are barely any larger.

Bluetooth Mesh for flexible building solutions

The DIMAX 540 APP communicates via a Bluetooth Mesh network. Multiple devices can be connected to a shared network. The configuration of a connected device is automatically transferred to all other DIMAX 540 APPs. A central control unit in the control cabinet is not required.

This offers significant advantages:

  • Scalable installation
  • High reliability
  • No central control required
  • Easy expansion of existing systems

Configuration via app

Configuration via the app enables customized light control through scenes and astro programs. Communication between devices via Bluetooth allows, for example, dimming multiple lights or turning off all lights. Operation is performed either via the app or via the push button.

  • A scene can dim all assigned lights in the room simultaneously
  • Mood scene: Dining, working, or relaxing with dimmed lighting​
  • Astro function: Lighting automatically turns on at sunset and off at sunrise

Without the app, a single light can be dimmed and the minimum brightness set.
