MSM II-Switch with M12 Connector

• Optimized for industrial control architectures
• Accustomed SCHURTER Metal Line quality
• IP Protection Class IP67

With the new switch from the MSM II family with M12 connector (8 pins), Schurter is focusing on a solution that has been specially developed for demanding industrial and commercial applications. Thanks to the M12 connector system, robust construction, and integrated RGB illumination, this switch combines maximum reliability, functionality, and modern design in a compact unit.

The standardized M12 connector ensures fast, secure, and error-free installation—without any complicated wiring. Thanks to the fixed pin assignment, wiring errors are effectively avoided, which not only simplifies installation but also speeds it up considerably.

The mechanical design is made for permanent industrial use—shockproof, vibration-resistant, and resistant to tough environments. This means the switch will keep working reliably for years, even in extreme conditions.

The three-color RGB illumination provides clear status indication or individual signals. Example: green = active; red = off; flashing orange = error condition. This makes the switch ideal for machine controls, control systems, or user interfaces.

The new Schurter MSM II M12 switch is suitable for applications where installations must be made quickly, easily, and safely. It is used in industrial automation, machine and plant engineering, as well as in public and commercial areas where clear signaling and high reliability are required.
