From classic and simple to extravagant: In System M, surfaces and materials can be combined almost without limits. Without having to change the inserts, the frames and switches are easily interchangeable. This makes System M one of the most flexible switch programs, adapting 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 while ensuring maximum safety in the installation process.
