FAQ: rond 24V Potential-Free Push Button
What is a potential-free push button?
A potential-free (or "dry contact") push button is a mechanical switch with no internal voltage of its own. Instead of carrying electrical power, it simply opens or closes a circuit, sending a signal to a separate control system. This makes it a safe, universal way to trigger automation interfaces — such as KNX push button interfaces or DALI-2 interfaces — without exposing the switch itself to live power.
How does the rond 24V push button work?
The rond 24V Trimless Push Button is a potential-free switch: pressing it doesn't send power through the button, it simply closes a contact that signals your connected automation or lighting system (e.g. a KNX or DALI-2 interface, or a compatible push-dim driver) to act. This keeps the switch itself voltage-free and safe, while your smart system handles the actual power switching.
Is the rond push button compatible with dimming?
Yes. The rond 24V push button supports dimming when paired with a compatible push-dim (switch-dim) driver. Because the button is potential-free, it sends a simple trigger signal rather than power, allowing it to work seamlessly with dimming systems.
What's the difference between this and a standard push button?
A standard push button typically carries voltage directly to a circuit. A potential-free button like the rond 24V doesn't — it only sends a dry signal to a separate control unit. This makes it safer, more flexible, and compatible with a wider range of smart home and building automation systems.
What size is the rond 24V push button, and does it come in a trimless design?
Yes. The rond 24V push button has a trimless design with a Ø48mm cutout, giving it a fully flush, minimalist finish once installed. Achieving this look does require precise installation of the installation ring — see below for wall compatibility.
Can it be installed in any wall type?
The rond 24V Push Button is suitable for:
- wood panels
- veneer panels
- stone and marble panels
What installation kit do I need?
The Backfit Holder installs into cabinets and furniture, and into wood, veneer and stone panels. Suitable for panel depths of 19mm and with access to the back of the panel. Where the panel is thicker or thinner than 19mm, the panel can be machine cut or packed out to the correct depth.
PLEASE NOTE: Not suitable for brickwork or plasterboard, or for use with the Multifit Holder which installs which is suitable for panel depths of 10-30mm.
Does the rond push button have a built-in temperature sensor?
Yes. It includes an invisible NTC temperature sensor, integrated seamlessly into the minimalist design without affecting its trimless finish.
Can the button orientation be adjusted after installation?
Yes. The push button is rotatable every 45°, so it can be aligned to your preferred orientation regardless of how the housing box was originally installed.
What configurations and finishes are available?
- Configurations: Two-fold or four-fold button layouts
- Finishes: Basic (white, black, cream, grey), Aluminium (white, aluminium), Brass (brushed nickel, brushed brass, light bronze, dark bronze, canon de fusil dark, canon de fusil light)
What are the RAL colours for the white and cream cover plates?
The white cover plate is RAL 9003, and the cream cover plate is RAL 1013.
Is it compatible with other rond products?
Yes. The rond 24V push button is compatible with all rond 2.0 installation kits, making it easy to combine with other rond switches and sensors in the same installation.
What if I need to access the wiring after installation?
The rond retrofit ring is designed with a dedicated removal tool, so electrical connections stay accessible even after plastering — making future maintenance or adjustments straightforward.
