Why Choose the ABB M3SS4-20R Selector Switch?
The ABB M3SS4-20R is a durable 3-position maintained selector switch designed for operator control and mode selection in industrial machinery, electrical control panels and automation systems. Part of the ABB Modular plastic pilot device range, it features a red long-handle actuator and chrome-plastic bezel for clear identification and dependable manual operation.
The M3SS4-20R uses a maintained operating principle, with three selectable positions identified as A, B and C. Each selected position remains in place until the operator deliberately moves the handle, making this selector particularly suitable for applications requiring stable machine mode or function selection.
Designed for standard 22 mm class control-panel mounting, the M3SS4-20R integrates easily into industrial operator stations and machine panels. Its non-illuminated construction, long handle and IP66 front protection provide a straightforward and robust interface, while the modular design allows compatible ABB contact blocks to be selected separately for the required control circuit.

Reliable Maintained Selection for Industrial Machinery
Maintained selector switches provide operators with a straightforward way to select machine operating modes or control states that must remain active until deliberately changed. The ABB M3SS4-20R provides three maintained positions, enabling multiple operating states or functions to be selected from one compact panel-mounted operator.
As part of ABB's Modular pilot device system, the M3SS4-20R can be combined with compatible contact blocks and mounting components to create an operator control assembly suited to the electrical and operational requirements of industrial machinery and automation equipment.
Typical Applications
- Industrial machinery control panels.
- Factory automation systems.
- Machine operating-mode selection.
- Production and processing equipment.
- Material handling and conveyor systems.
- OEM machinery and operator control stations.
