Why Choose the ABB M2SS5-21Y Selector Switch?
The ABB M2SS5-21Y is a robust 2-position illuminated selector switch designed for operator control and visual signalling in industrial machinery, electrical control panels and automation systems. Part of the ABB Modular Plastic pilot device range, it features a yellow long-handle rotary actuator with a chrome plastic front bezel for a clear and professional operator interface.
The M2SS5-21Y provides maintained A/C selector operation, allowing the selected position to remain active until the operator deliberately changes it. Its long-handle actuator provides positive manual selection, while its suitability for illumination enables clear visual indication of machine states, operating modes and control functions.
Designed for standard 22 mm pilot-device mounting, the M2SS5-21Y integrates easily into industrial control panels and machinery. Its IP66 front protection and NEMA 4X rating support dependable use in demanding environments, while ABB's modular construction allows compatible contact and illumination components to be configured for the required control circuit.

Reliable Illuminated Control for Industrial Machinery
Maintained selector switches are used where an operator needs to select a machine state, operating mode or process function and have that selection remain active without continuously holding the actuator. The ABB M2SS5-21Y provides this functionality through its two-position A/C arrangement and long rotary handle, giving operators a clear and intuitive means of selecting the required state.
The yellow operator is suitable for illumination to add visual signalling capability, while ABB's modular pilot-device architecture allows compatible holders, contact blocks and LED or lamp components to be combined according to the requirements of the application. This makes the M2SS5-21Y suitable for new machinery, OEM control panels and compatible ABB pilot-device installations.
