From classic-simple to extravagant: In System M, surfaces and materials can be combined almost without limits. Without having to change the inserts, frames and rockers 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 make installation significantly easier – all while ensuring maximum safety during the installation process.
