Why Choose the ABB M2SSK3-303 Key Selector Switch?
The ABB M2SSK3-303 is a robust 2-position momentary key-operated selector switch designed for industrial machinery, automation systems and electrical control panels. Part of the ABB modular pilot device range, it combines key-controlled operation with a black key actuator and chrome-metal bezel for dependable manual control in demanding industrial applications.
This selector switch uses key code 3433-E and is configured so that the key can be removed in position B only. Its momentary switching action provides spring-return operation rather than remaining latched in the actuated position, making it suitable for authorised command, reset and temporary control functions.
The M2SSK3-303 is a non-illuminated operator designed for a standard 22 mm panel mounting hole. Its modular construction allows suitable ABB contact blocks to be selected separately according to the required control circuit, while IP66 front protection and a NEMA 4X rating support reliable use in demanding industrial environments.

Secure Momentary Control for Industrial Machinery
Key-operated selector switches provide a practical way to restrict specific machine commands to personnel possessing the appropriate key. This helps prevent inadvertent or unauthorised operation while maintaining a simple and familiar control interface for authorised operators and maintenance personnel.
The ABB M2SSK3-303 combines key-controlled access with momentary operation, making it suitable for commands that should only remain active while deliberately actuated. ABB's modular pilot-device architecture also allows the required contact blocks to be selected independently to suit the electrical control arrangement.
Typical Applications
- Industrial machinery control panels.
- Authorised momentary machine commands.
- Reset and control functions.
- Maintenance and service controls.
- Automation and production equipment.
- Motor and process control panels.
- OEM machinery and operator control stations.
