Why Choose the ABB M2SSK1-302 Selector Switch?
The ABB M2SSK1-302 is a two-position key-operated selector switch from ABB's modular 22 mm pilot-device range, designed for industrial machinery, control panels and automation systems. Its key-operated interface is particularly useful where deliberate, controlled access to a machine function or operating state is required.
The M2SSK1-302 provides two maintained selector positions, allowing the selected operating state to remain active until the key mechanism is deliberately moved to the alternative position. The key-operated design helps distinguish authorised or intentional control functions from routine pushbutton and handle-operated commands.
Designed for standard 22 mm panel mounting, the M2SSK1-302 uses ABB's modular pilot-device architecture, allowing compatible holders and contact blocks to be selected according to the required electrical switching arrangement. This makes it a flexible operator-control solution for machinery, process equipment and industrial electrical panels.
Key Advantages
- Key-operated selector control supports deliberate operation of important machine functions.

Controlled Two-Position Selection for Industrial Machinery
Key-operated selector switches are commonly used where a machine function should require deliberate access rather than unrestricted operation from a conventional rotary handle. The ABB M2SSK1-302 provides two maintained operating positions, enabling a selected control state to remain mechanically set until the key-operated selector is intentionally changed.
The modular ABB design allows the operator to be combined with compatible contact blocks selected according to the required electrical control logic. This makes the M2SSK1-302 suitable for machine mode selection, controlled enable functions and other industrial applications where key-operated two-state control is advantageous.
Typical Applications
- Industrial machinery control panels.
- Key-controlled machine mode selection.
- Operator control stations and consoles.
- Controlled enable and disable functions.
- Production and process automation equipment.
- Material handling and conveyor control systems.
- OEM machinery and electrical control assemblies.
