Why Choose the ABB M2SS1-21Y Selector Switch?
The ABB M2SS1-21Y, ABB order code 1SFA611200R2103, is a modular two-position illuminated selector switch operator designed for industrial machinery, automation systems and operator control panels. Part of ABB's modular Pilot Devices range, it combines a compact short-handle actuator with yellow illumination and a chrome-effect plastic bezel.
The M2SS1-21Y features a yellow short-handle actuator with maintained two-position operation. Its B and C maintained positions allow the selector to remain in the chosen position after the operator releases the handle, making it suitable for machine modes, operating states and other functions requiring a persistent manual selection.
Designed for standard 22 mm industrial pilot-device mounting, the M2SS1-21Y provides IP66 front protection and a NEMA 4X enclosure rating at the front when correctly installed. Its modular design allows compatible ABB contact and illumination components to be selected according to the required electrical switching and signalling functions.
Key Advantages
- Compact two-position illuminated selector switch operator for industrial control applications.
- Yellow short-handle actuator provides clear visual identification.

Maintained Selection and Visual Indication for Industrial Machinery
Maintained selector switches provide operators with a clear method of choosing between machine modes, process functions or operating states that need to remain selected. The ABB M2SS1-21Y stays in its selected B or C position after the handle is released, eliminating the need for the operator to hold the control in position.
The M2SS1-21Y combines this maintained switching action with a yellow illuminated short handle and chrome-effect plastic bezel. As part of ABB's modular pilot-device system, the operator can be combined with suitable switching and illumination components to create a control arrangement tailored to the machinery or automation application.
Typical Applications
- Industrial machinery mode selection.
- Operator stations and control consoles.
- Manufacturing and production equipment.
- Manual and automatic mode selection circuits.
- Conveyor and material handling systems.
