Why Choose the ABB M3SS3-20B Selector Switch?
The ABB M3SS3-20B is a robust 3-position maintained/momentary selector switch designed for operator control and command functions in industrial machinery, electrical control panels and automation systems. Part of the versatile ABB Modular plastic pilot device range, it features a black short-handle actuator with a chrome-plastic bezel for a durable and professional operator interface.
The M3SS3-20B uses a combined maintained and momentary operating principle, with positions A and B fixed and spring return from position C to B. This configuration allows an operator to retain one selected position while using the third position as a temporary command that automatically returns to the centre position when released.
Designed for standard 22 mm control-panel mounting, the M3SS3-20B is suitable for integration into machinery panels and operator stations. The selector is non-illuminated and provides IP66 front protection, while its modular construction allows compatible ABB contact blocks and holders to be selected separately for the required control circuit.
Key Advantages
- 3-position maintained/momentary selector switch for flexible machine control.
- Positions A and B are maintained, with spring return from C to B.
- Black short-handle actuator provides straightforward manual operation.
- Durable chrome-plastic bezel for a professional control-panel finish.
- Standard 22 mm panel mounting simplifies industrial installation.
- IP66 front protection supports reliable use in demanding environments.
Key Features
- ABB M3SS3 Modular selector switch.
- 3 operating positions.
- Maintained/momentary operating action.
- Maintained positions A and B.
- Spring return from C to B.
- Short-handle actuator.
- Black actuator colour.
- Non-illuminated design.
- Chrome-plastic bezel.
- Supplied without contact block.
Flexible Maintained and Momentary Machine Control
Three-position selector switches provide operators with an intuitive way to select machine modes and issue control commands. The ABB M3SS3-20B combines maintained positions with a spring-return position, making it particularly useful where a machine function must remain selected until deliberately changed while another function requires only temporary actuation.
As part of ABB's Modular pilot device system, the M3SS3-20B can be combined with compatible contact blocks and holders to create an operator control assembly matched to the electrical requirements of industrial machinery and automation equipment.
Typical Applications
- Industrial machinery control panels.
- Factory automation systems.
- Machine mode and function selection.
- Production and processing equipment.
- Material handling and conveyor systems.
- OEM machinery and operator control stations.
