Why Choose the ABB M3SS1-31Y Selector Switch?

The ABB M3SS1-31Y is a robust 3-position illuminated selector switch designed for dependable manual control and operating-mode selection in industrial machinery, automation systems and electrical control panels. As part of ABB’s modular pilot device range, it combines a short-handle actuator with maintained operation and a highly visible yellow illuminated control element.

This selector switch uses an A-B-C maintained operating principle, allowing the actuator to remain in any of its three selected positions until deliberately changed by the operator. The yellow illuminated actuator provides clear visual identification, while the chrome metal bezel gives the operator a durable finish suited to industrial control stations.

The M3SS1-31Y is designed for a standard 22 mm panel mounting hole and is supplied as a modular selector switch operator without a contact block. Its modular construction allows the appropriate ABB contact and illumination components to be selected separately for the required control circuit.

Key Advantages

  • Industrial 3-position maintained selector switch for operator control.
  • A-B-C maintained positions support clear three-state mode selection.
  • Yellow illuminated short handle provides clear visual identification.
  • Durable chrome metal bezel for industrial panel applications.
  • Standard 22 mm panel mounting simplifies integration into control stations.
  • Modular design enables flexible selection of compatible contact and illumination components.

Key Features

  • ABB M3SS1 modular selector switch.
  • 3-position maintained operation.
  • A-B-C maintained positions.
  • Short-handle actuator.
  • Yellow illuminated control element.
  • Chrome metal bezel.
  • No contact block included.
  • 22 mm mounting hole.
  • Designed for modular industrial pilot-device assemblies.

Reliable Three-Position Operator Control

Three-position selector switches are commonly used where an operator must choose between three defined machine states or operating modes. The maintained action of the ABB M3SS1-31Y keeps the selected A, B or C position active until the handle is intentionally moved, making it suitable for functions such as manual-off-automatic selection, operating-mode selection and process control.

Its modular construction allows the selector switch operator to be combined with compatible ABB contact blocks and illumination components according to the electrical requirements of the application. This provides flexibility for machine builders, panel builders and automation engineers when configuring operator interfaces.

Typical Applications

  • Industrial automation control panels.
  • Manual-off-automatic control circuits.
  • Machine operating-mode selection.
  • Production and processing equipment.
  • Motor and process control panels.
  • OEM machinery and equipment.
  • Operator stations and control consoles.
