From classic-simple to extravagant: In the System M, surfaces and materials can be combined almost without limits. Without having to change the inserts, frames and switches are easily interchangeable. This makes System M one of the most flexible switch programs that adapts to all design preferences. Even more flexibility and comfort are provided by the new QuickFlex switch and socket bases. These new flush-mounted inserts significantly simplify installation – all while ensuring maximum safety during the installation process.
