Why Choose the ABB M3SS8-30B Selector Switch?
The ABB M3SS8-30B is a robust 3-position maintained/momentary selector switch designed for industrial machinery, automation equipment and electrical control panels. Part of ABB's Modular pilot device range, it features a black long-handle actuator, non-illuminated construction and a durable chrome-metal bezel.
The M3SS8-30B combines maintained positions B and C with a momentary A position that spring-returns to B. This operating arrangement provides two stable selections together with a temporary command, allowing multiple machine-control functions to be handled from one compact operator.
Designed for standard 22 mm control-panel mounting, the M3SS8-30B provides IP66 front protection and NEMA Type 4X protection for demanding industrial environments. Its modular construction allows compatible ABB contact blocks to be selected separately according to the required electrical switching configuration.
Key Advantages
- 3-position maintained/momentary operation combines stable and temporary control functions.
- Positions B and C are maintained for persistent operating selections.
- Position A spring-returns to B for a temporary machine command.
- Black long-handle actuator provides convenient and intuitive operation.
- Durable chrome-metal bezel provides a robust industrial panel finish.
- IP66 front and NEMA Type 4X protection support demanding control-panel environments.

Flexible Maintained and Momentary Machine Control
The ABB M3SS8-30B combines maintained and spring-return functions within a single three-position operator. Positions B and C remain selected after the handle is released, while position A provides a temporary command and automatically returns to position B when released.
This operating arrangement is well suited to machinery where stable operating selections need to be combined with a momentary control command. ABB's modular pilot-device architecture also enables compatible contact blocks to be selected according to the electrical requirements of the machine or automation system.
Typical Applications
- Industrial machinery control panels.
- Machine operating-mode selection.
- Temporary machine command functions.
- Factory automation equipment.
- Material handling and conveyor systems.
- OEM machinery and operator control stations.
