ABB M3SS4-21G is a green illuminated 3-position maintained A-B-C selector switch with a long rotary handle, chrome plastic bezel and IP66 front protection for 22 mm industrial control-panel applications.
£8.96
The ABB M3SS4-21G is a robust 3-position illuminated maintained selector switch designed for operator control and visual signalling in industrial machinery, automation systems and electrical control panels. Part of ABB's Modular Plastic pilot device range, it features a green long rotary handle with a chrome plastic bezel for a distinctive and professional operator interface.
The M3SS4-21G provides maintained A-B-C operation, with all three positions remaining selected until the operator deliberately moves the handle. Its long-handle actuator provides positive rotary operation, while the green operator is suitable for illumination to provide clear visual status indication when used with a compatible ABB illumination component.
Designed for standard 22 mm pilot-device mounting, the M3SS4-21G provides IP66 front protection and NEMA 4X protection for demanding industrial environments. ABB's modular architecture allows compatible contact blocks and illumination components to be selected separately according to the required control-circuit configuration.
Three-position maintained selector switches provide a straightforward method of selecting between multiple machine states, operating modes or process functions from a single panel-mounted operator. The ABB M3SS4-21G provides three maintained A-B-C positions, allowing each selected state to remain mechanically latched until the operator deliberately moves the long rotary handle.
The green operator is suitable for illumination to support visual signalling, while the chrome plastic bezel provides a clean industrial panel appearance. ABB's modular pilot-device architecture allows compatible contact blocks and illumination components to be configured according to the required electrical control logic, making the M3SS4-21G suitable for new machinery, OEM panels and compatible ABB pilot-device installations.
