ABB M3SSK1-103 is a three-position maintained key selector switch with a Ronis 3433-E key, key removal in all A-B-C positions, black plastic bezel and IP66 front protection for industrial control applications.
Why Choose the ABB M3SSK1-103 Key Selector Switch?
The ABB M3SSK1-103 is a three-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 selection between three defined machine, process or operating states.
The M3SSK1-103 provides three maintained A-B-C positions and uses a Ronis 3433-E key, ABB key code 73. The key can be removed in all three positions, allowing the selected operating state to remain mechanically set after the key has been withdrawn.
This non-illuminated operator features a black key actuator and black plastic bezel, with IP66 front protection for demanding industrial environments. It is supplied without a contact block, allowing compatible ABB modular holders and contact blocks to be selected according to the required electrical switching arrangement.
Key Advantages
Three-position maintained operation provides stable A-B-C selection between three control states.
Ronis 3433-E key with ABB key code 73 provides a defined key-operated configuration.
Key can be removed in all three selector positions.
Black plastic bezel provides a practical industrial operator-panel finish.
IP66 front protection supports use in demanding industrial control environments.
ABB modular construction allows compatible contact blocks to be selected for the required control circuit.

Controlled Three-Position Selection for Industrial Machinery
Three-position key selector switches provide a deliberate operator interface for machinery and processes requiring controlled selection between multiple operating states. The ABB M3SSK1-103 provides maintained A-B-C operation, so the selected position remains mechanically set until the operator intentionally moves the key selector to another position.
The Ronis 3433-E key can be removed in A, B or C, allowing any of the three maintained operating states to remain selected after key removal. Combined with ABB's modular contact-block system, this makes the M3SSK1-103 suitable for machine mode selection, process control and other industrial applications requiring stable three-state key operation.
