Why Choose the ABB M2SSK2-102 Key-Operated Selector Switch?
The ABB M2SSK2-102 is a robust two-position key-operated selector switch designed for controlled operation of industrial machinery, automation systems and electrical control panels. Part of the ABB modular pilot devices range, it provides a maintained switching action with key-controlled access, helping restrict operation to authorised personnel.
This selector switch features two maintained positions and uses key code 421. The key can be removed in the B position only, providing a defined key-removal position for applications where controlled machine or process selection is required. The maintained mechanism holds the selected position until the key operator is deliberately turned.
The M2SSK2-102 has a black key actuator and black plastic bezel, is non-illuminated and is designed for a standard 22 mm mounting hole. Its modular construction allows it to be combined with appropriate ABB contact blocks, while IP66 front protection supports dependable operation in demanding industrial environments.
Key Advantages
- Two-position maintained key-operated selector switch for controlled industrial operation.

Controlled Machine and Process Selection
Key-operated selector switches are commonly used where access to a machine function or operating state needs to be restricted. Requiring a physical key helps prevent casual or unintended operation and provides a straightforward method of controlling access to selected machine functions.
The ABB M2SSK2-102 combines this controlled operation with a maintained two-position mechanism. Its modular design allows appropriate ABB contact blocks to be selected according to the electrical control requirements of the installation, while the key-removal arrangement provides a clearly defined secured position.
Typical Applications
- Industrial machinery control panels.
- Authorised machine operating-mode selection.
- Automation and production equipment.
- Maintenance and service control functions.
- Motor and process control panels.
- OEM machinery and operator control stations.
