Why Choose the ABB M3SS8-20B Selector Switch?
The ABB M3SS8-20B is a robust 3-position maintained/momentary selector switch designed for dependable operator control in industrial machinery, automation systems and electrical control panels. Supplied under ABB order code 1SFA611217R2006, it forms part of ABB’s modular 22 mm pilot device range and provides a durable interface for machine and process control applications.
The M3SS8-20B features a black long-handle actuator with a chrome-plastic bezel. Its three-position A-B-C operating arrangement provides fixed B and C positions with spring return from position A to position B, combining maintained selection with a momentary command function in a single operator.
Designed for industrial control-panel applications, the M3SS8-20B is a non-illuminated modular selector switch supplied without a contact block. Compatible ABB contact blocks and mounting components can therefore be selected separately to create the required electrical switching configuration.

Reliable Operator Control for Industrial Machinery
Selector switches provide operators with a clear and intuitive method of selecting machine modes and issuing control commands. The ABB M3SS8-20B combines fixed B and C positions with a momentary A position that automatically returns to B, making it suitable for control schemes where maintained operating selections are complemented by a temporary command.
ABB’s modular pilot device system allows the selector switch actuator and compatible contact blocks to be configured according to the application. The M3SS8-20B combines a practical long-handle operator with a chrome-plastic bezel and modular construction, making it suitable for industrial control panels, operator stations and OEM machinery.
Typical Applications
- Industrial machinery control panels.
- Machine mode and function selection.
- Maintained and momentary command functions.
- Factory automation systems.
- Motor and process control panels.
- Material handling and production machinery.
- OEM machinery and electrical control systems.
