Why Choose the ABB M3SS3-10U Three-Position Selector Switch?
The ABB M3SS3-10U (1SFA611212R1007) is a durable and reliable three-position non-illuminated selector switch designed for industrial machinery, electrical control panels and automation systems. As part of the ABB Modular Range of pilot devices, it features a grey short-handle actuator, black plastic bezel and a combination of maintained and momentary switching positions for flexible manual control.
The M3SS3-10U provides three operating positions with spring return from position C to position B. Positions A and B are maintained, while position C is momentary and automatically returns to the centre when released. This operating arrangement is particularly suitable for applications requiring a maintained operating selection together with a temporary command, such as machine mode selection, manual override and equipment control.
Designed for a standard 22 mm panel mounting hole, the ABB M3SS3-10U combines compact construction with dependable mechanical operation. Its modular design supports compatible ABB contact blocks and mounting holders, enabling the switching configuration to be adapted to specific control requirements. The non-illuminated grey actuator and black plastic bezel provide a clear, practical operator interface for industrial environments.

Reliable Maintained and Momentary Control for Industrial Machinery
Industrial selector switches such as the ABB M3SS3-10U provide a practical interface between machine operators and electrical control systems. Its three-position mechanism combines maintained switching with a momentary spring-return function. Positions A and B remain selected until manually changed, while position C automatically returns to B when the handle is released. This arrangement allows a single operator to provide both a retained selection and a temporary control command.
The ABB M3SS3-10U is designed for integration with compatible ABB Modular Range contact blocks, allowing electrical switching functions to be configured for PLC inputs, contactor control circuits and industrial automation systems. Its grey short-handle actuator, black plastic bezel and standard 22 mm mounting format make it suitable for machine operator panels, control cabinets and industrial equipment requiring dependable manual switching.
Typical Applications
- Industrial machinery operator control panels.
- Maintained operating mode selection with momentary command functions.
- Machine control and manual override circuits.
