Why Choose the ABB M3SS5-20B Selector Switch?
The ABB M3SS5-20B is a robust 3-position non-illuminated selector switch designed for reliable operator control in industrial machinery, automation systems and electrical control panels. Supplied under ABB order code 1SFA611214R2006, it forms part of ABB’s modular plastic pilot device range and combines flexible configuration with dependable mechanical performance.
The M3SS5-20B features a black long-handle actuator and an attractive chrome-plastic bezel. Its three-position A-B-C operating arrangement uses maintained/momentary action with spring return from positions A and C to the centre position B, making it well suited to temporary directional and command functions where the actuator should automatically return to centre.
Designed for standard 22 mm industrial pilot device applications, the M3SS5-20B provides IP66 front protection for dependable service in demanding environments. Its modular construction allows compatible ABB contact blocks and holders to be selected separately according to the electrical switching requirements of the application.

Reliable Operator Control for Industrial Machinery
Selector switches provide operators with a clear and intuitive method of issuing machine commands and selecting control functions. The ABB M3SS5-20B uses a three-position arrangement with spring return from both outer positions to the centre, making it particularly suitable for temporary commands such as forward/reverse, raise/lower or left/right control when used with an appropriately designed control circuit.
ABB’s modular pilot device system allows the selector switch actuator, holder and contact blocks to be configured according to the application. The M3SS5-20B combines durable industrial construction, high front protection and straightforward modular installation, making it suitable for both new machinery and replacement control-panel applications.
Typical Applications
- Industrial machinery control panels.
- Forward and reverse control circuits.
- Raise and lower machine controls.
- Factory automation systems.
- Motor and process control panels.
- Material handling and production machinery.
- OEM machinery and electrical control systems.
