Why Choose the ABB M3SS6-20B Selector Switch?
The ABB M3SS6-20B is a versatile three-position selector switch operator designed for industrial control panels, machinery and automation systems. Part of ABB’s modular pilot device range, it features a black long-handle actuator with a chrome plastic bezel, providing dependable manual control and a durable control-panel interface.
The M3SS6-20B combines maintained and momentary operation. Positions A and B are maintained, while position C provides spring return to B. This operating principle enables one selector to provide both retained mode selection and a temporary control command.
ABB order code 1SFA611215R2006 identifies this exact M3SS6-20B selector switch. The operator is non-illuminated, designed for a standard 22 mm mounting hole and supplied without a contact block, allowing compatible ABB contact blocks and holders to be selected according to the required control circuit.

Flexible Maintained and Momentary Machine Control
Selector switches provide operators with a straightforward physical interface for selecting machine modes and issuing control commands. The ABB M3SS6-20B combines maintained and spring-return functions, allowing a single operator to support both retained selections and temporary commands within an industrial control system.
Positions A and B remain selected until the handle is deliberately moved, while position C automatically returns to B when released. Its modular ABB construction allows compatible contact blocks to be selected according to the switching requirements of the application.

- Industrial machine control panels.
- Factory automation equipment.
- Operating-mode selection systems.
- Manual machine control functions.
- Conveyors and material handling equipment.
- Production and process machinery.
- OEM machinery and electrical control systems.
