Why Choose the ABB M2SSK2-301 Key Selector Switch?
The ABB M2SSK2-301 is a two-position maintained key selector switch from ABB's modular 22 mm pilot-device range, designed for industrial machinery, control panels and automation systems. Its key-operated interface provides deliberate manual selection where controlled access to a machine function or operating state is required.
This selector switch features a black key-operated actuator, 455 key configuration and two stable maintained positions. The key can be removed in the designated 0 position, providing a practical key-retention arrangement for machine mode, enable and controlled-access functions.
Designed for standard 22 mm panel mounting, the M2SSK2-301 combines a chrome-metal front ring with non-illuminated construction and IP66 front protection. It is supplied without a contact block, allowing compatible ABB modular contact blocks to be selected according to the required electrical switching arrangement.
Key Advantages
- Two-position maintained key operation provides stable selection between two control states.
- 455 key configuration provides a defined key-operated interface for controlled functions.
- Key removal in the designated 0 position supports controlled key-retention applications.
- Chrome-metal front ring provides a durable industrial panel finish.
- IP66 front protection supports installation in demanding industrial environments.
- ABB modular construction allows compatible contact blocks to be selected for the required control circuit.

Controlled Maintained Selection for Industrial Machinery
Key-operated selector switches provide a deliberate operator interface for machine functions where access or operating-state selection should be controlled. The ABB M2SSK2-301 provides two stable maintained positions, so the selected state remains mechanically set until the operator deliberately changes the key selector.
The M2SSK2-301 combines a 455 key configuration with key removal in the designated 0 position, a chrome-metal front ring and IP66 front protection. As part of ABB's modular pilot-device platform, it can be combined with compatible contact blocks according to the required electrical control logic.
