Why Choose the ABB M3SS2-21Y Selector Switch?

The ABB M3SS2-21Y is a three-position momentary illuminated selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular 22 mm pilot device range, it features a yellow short-handle rotary actuator with a chrome-plastic bezel for clear manual control and visual indication.

The M3SS2-21Y provides three selector positions with spring return from A and C to the centre B position. This momentary operating principle automatically returns the actuator to B when released from either outer position, making the switch well suited to temporary directional, adjustment and machine-command functions.

Designed for standard 22 mm panel mounting, the M3SS2-21Y is an illuminated modular operator supplied without a contact block. Its modular design allows compatible ABB contact and illumination components to be selected according to the required electrical control and indication function.

Key Advantages

  • Three-position momentary selector switch for industrial command functions.
  • Spring return from A and C to centre position B provides automatic return after operation.
  • Yellow illuminated short-handle actuator combines manual control with visual indication.
  • Chrome-plastic bezel provides a clean and durable operator interface.
  • Standard 22 mm panel mounting simplifies integration into industrial control stations.
  • Modular ABB construction allows the required contact and illumination components to be selected separately.
  • Compact design is suitable for machinery, process and OEM automation panels.

Key Features

  • ABB M3SS2 modular selector switch series.
  • Three-position momentary operation.
  • Spring return from A to B and from C to B.
  • Short-handle rotary actuator.
  • Yellow actuator colour.
  • Illuminated selector switch design.
  • Chrome-plastic bezel.
  • Supplied with no contact block.
  • 22 mm modular pilot-device format.
  • Product weight of approximately 0.015 kg.

Reliable Momentary Control for Industrial Machinery

Three-position momentary selector switches provide operators with temporary commands in either direction while automatically returning to a defined centre position. The ABB M3SS2-21Y returns from both outer positions A and C to centre position B when released, making it suitable for functions where a control command should remain active only while deliberately selected.

The M3SS2-21Y forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to configure the illuminated operator with compatible control components. Its yellow short-handle actuator, chrome-plastic bezel and standard 22 mm format provide a compact operator interface for industrial machinery and automation equipment.

Typical Applications

  • Industrial machinery control panels.
  • Forward / centre / reverse command functions.
  • Raise / neutral / lower control functions.
  • Jogging and temporary machine commands.
  • Manufacturing and production equipment.
  • Material handling and conveyor systems.
  • OEM machinery and industrial automation systems.
