Why Choose the ABB M3SS5-21Y Selector Switch?
The ABB M3SS5-21Y is a robust 3-position illuminated selector switch designed for momentary operator control in industrial machinery, electrical control panels and automation systems. Part of the ABB Modular pilot device range, it features a yellow illuminated long-handle actuator with a chrome-plastic bezel for clear identification and dependable operation.
The M3SS5-21Y uses a momentary operating principle with spring return from positions A and C to the centre B position. This configuration enables temporary commands to be issued in either direction while automatically returning the selector to its central position when the operator releases the handle.
Designed for standard 22 mm control-panel mounting, the M3SS5-21Y provides an intuitive operator interface for machinery and automation equipment. Its yellow actuator supports clear visual identification, while the modular construction allows compatible ABB contact blocks, holders and illumination components to be selected according to the requirements of the control circuit.

Reliable Momentary Control for Industrial Machinery
Momentary selector switches provide machine operators with a straightforward method of issuing temporary directional or process commands. The ABB M3SS5-21Y provides two momentary selections around a central resting position, automatically returning from either outer position to B when released.
This operating arrangement makes the M3SS5-21Y well suited to functions such as forward/reverse, raise/lower and left/right commands. As part of ABB's Modular pilot device system, it can be combined with compatible contact and illumination components to create an operator assembly matched to the requirements of industrial machinery and automation systems.
Typical Applications
- Industrial machinery control panels.
- Forward and reverse machine commands.
- Raise and lower control functions.
- Material handling and conveyor systems.
- Factory automation equipment.
- OEM machinery and operator control stations.
