1SFA611202R1007 ABB M2SS3-10U 2-Position Momentary Selector Switch

Why Choose the ABB M2SS3-10U Selector Switch?

The ABB M2SS3-10U is a two-position momentary selector switch operator designed for industrial machinery, control panels and operator stations. Part of ABB's modular plastic 22 mm pilot-device range, it provides a compact rotary command interface for applications requiring automatic spring-return operation.

The M2SS3-10U features a grey short rotary handle and black plastic bezel. Its momentary switching action uses a B/C two-position configuration with spring return, making it suitable for temporary machine commands where the selector should automatically return to its normal position after release.

Designed for a 22 mm mounting hole, the M2SS3-10U provides IP66 front protection and a NEMA 4X front protection classification. The operator is non-illuminated and forms part of ABB's modular pilot-device system, allowing compatible contact blocks to be selected according to the required electrical switching function. ABB order code 1SFA611202R1007 identifies this exact M2SS3-10U Selector Switch.

Key Advantages

• Two-position momentary operation provides a straightforward rotary command interface.
• Spring-return action automatically restores the selector after the temporary command is released.
• Grey short rotary handle provides clear identification and convenient operation.
• Non-illuminated design is ideal for command functions where integral visual indication is unnecessary.
• Black plastic bezel coordinates with ABB's modular plastic pilot-device range.
• IP66 front protection supports use in demanding industrial environments.
• NEMA 4X front protection provides an additional environmental protection classification.
• Standard 22 mm mounting format simplifies integration into industrial control panels.

Momentary Rotary Control with Automatic Spring Return

Momentary selector switches are suited to control functions where a rotary command should only remain active while deliberately selected. The ABB M2SS3-10U provides a two-position spring-return interface, automatically restoring the selector after the temporary command is released and helping prevent an unintended command from remaining selected.

The grey short handle provides a compact operator interface, while the black plastic bezel integrates with ABB's modular pilot-device system. Compatible contact blocks can be selected separately according to the electrical requirements of the machine or process, providing flexibility for machine builders, panel builders and automation engineers.

Typical Applications

• Industrial machinery momentary command functions.
• Machine control panels and operator stations.
• Manual machine-control functions.
• Manufacturing and production equipment.
• Conveyor and material handling systems.
• Process control and automation equipment.
• OEM machinery and machine-building applications.
