Why Choose the ABB M2SS5-20U Selector Switch?
The ABB M2SS5-20U is a robust two-position maintained selector switch operator designed for industrial control panels, machinery and automation systems. Part of ABB's modular 22 mm pilot device range, it features a distinctive grey long-handle rotary actuator for clear and dependable manual control.
The M2SS5-20U uses maintained operation, allowing the selector to remain in the chosen position until it is manually changed. Its two maintained positions are designated A and C, making it suitable for mode selection, machine control and other industrial command functions where a stable selected state is required.
Designed for a standard 22 mm mounting hole, the M2SS5-20U combines a non-illuminated grey actuator with a chrome-plastic bezel. Its front provides IP66 protection, while the modular operator is supplied without a contact block so the required contact arrangement can be selected separately for the application.

Reliable Selector Control for Industrial Machinery
Selector switches provide operators with a straightforward mechanical interface for choosing between predefined machine or process states. The maintained action of the ABB M2SS5-20U keeps the long-handle actuator in its selected position until another position is deliberately chosen, providing clear and predictable manual control.
The M2SS5-20U forms part of ABB's modular pilot-device system, allowing panel builders and machine manufacturers to combine the operator with compatible holders and contact blocks to suit the required electrical control function. Its standard 22 mm mounting format, robust construction and IP66 front protection make it well suited to industrial operator interfaces.
