Why Choose the ABB M3SS1-31C Selector Switch?
The ABB M3SS1-31C is a robust three-position maintained illuminated selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular 22 mm pilot device range, it features a clear short-handle rotary actuator and chrome-metal bezel for dependable manual selection and visual indication.
The M3SS1-31C provides three maintained positions, designated A, B and C, allowing the actuator to remain in the selected position until deliberately moved. This maintained operating principle makes it suitable for machine-mode selection, process control and other industrial applications requiring three stable command positions.
Designed for a standard 22 mm mounting hole, the M3SS1-31C combines an illuminated clear actuator with a durable chrome-metal bezel and IP66 front protection. The operator is supplied without a contact block, enabling compatible ABB modular contact and illumination components to be selected for the required control function.

Reliable Three-Position Control for Industrial Machinery
Three-position selector switches provide operators with a straightforward interface for choosing between multiple machine states or operating modes. The maintained action of the ABB M3SS1-31C keeps its short-handle actuator in the selected A, B or C position until another position is deliberately chosen, providing clear and predictable manual control.
The M3SS1-31C forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to combine the illuminated operator with compatible holders, contact blocks and illumination components. Its clear illuminated actuator, chrome-metal bezel, standard 22 mm mounting format and IP66 front protection make it suitable for industrial interfaces where both control and visible indication are required.
