Why Choose the ABB M2SS5-21L Selector Switch?
The ABB M2SS5-21L 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 blue long-handle rotary actuator with a chrome plastic bezel for a clear and professional operator interface.
The M2SS5-21L provides maintained A/C selector operation, allowing the selected position to remain active until the operator deliberately changes it. Its long rotary handle provides positive manual selection, while the blue illuminated design enables clear visual indication of machine states, operating modes and control functions.
Designed for standard 22 mm pilot-device mounting, the M2SS5-21L integrates easily into industrial control panels and machinery. Its IP66 front protection and NEMA 4X rating support dependable operation in demanding environments, while ABB's modular construction allows compatible holders, contact blocks and LED blocks to be selected according to the application.

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 M2SS5-21L provides this functionality through two maintained A/C positions and a long rotary handle that gives operators a clear and intuitive indication of the selected state.
The blue illuminated operator adds visual signalling capability, while ABB's modular pilot-device architecture allows compatible holders, contact blocks and LED blocks to be configured according to the requirements of the control circuit. This makes the M2SS5-21L suitable for new machinery, OEM control panels and compatible ABB pilot-device installations.
