Why Choose the ABB M3SSK1-102 Key Selector Switch?
The ABB M3SSK1-102 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 manual selection between three defined machine or process operating states.
This selector switch features a black key-operated actuator, 421 key code and maintained A-B-C operation. The key can be removed in all selector positions, providing flexible key-removal behaviour for applications where the selected operating state may need to remain set after the key has been withdrawn.
The M3SSK1-102 has a black plastic bezel and non-illuminated construction and is supplied without a contact block. Its ABB modular design allows compatible holders and contact blocks to be selected according to the required electrical switching arrangement, making it a flexible solution for industrial operator-control applications.
Key Advantages
- Three-position maintained key operation provides stable A-B-C selection between three control states.
- 421 key code provides a defined key configuration for the operator.
- Key can be removed in all three selector positions.
- Black plastic bezel provides a durable industrial operator-panel finish.
- Part of ABB's modular 22 mm pilot-device platform.
- Modular construction allows compatible ABB 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 applications requiring controlled selection between multiple machine functions or operating modes. The ABB M3SSK1-102 provides maintained A-B-C operation, so the selected state remains mechanically set until the key-operated selector is intentionally moved to another position.
The M3SSK1-102 uses ABB's 421 key code and permits key removal in every selector position. Combined with its black plastic bezel and modular contact-block architecture, this makes the operator suitable for machine mode, process selection and other industrial control functions requiring stable three-state key operation.

- Key-controlled machine mode selection.
- Operator control stations and consoles.
- Three-state process and function selection.
