1SFA611202R1006 ABB M2SS3-10B 2-Position Momentary Selector Switch

Why Choose the ABB M2SS3-10B Selector Switch?

The ABB M2SS3-10B is a two-position momentary selector switch operator designed for industrial machinery, control panels and operator stations. Part of ABB's modular plastic pilot-device range, it uses a short rotary handle to provide a straightforward manual command function in a standard industrial panel format.

The M2SS3-10B features a black short handle, black plastic bezel and non-illuminated design. Its operating principle provides spring return from position C to position B, so the selector automatically returns to its normal B position when released from C.

Designed for ABB's 22 mm modular pilot-device system, the M2SS3-10B uses a nominal 22.5 mm mounting hole and provides IP66 front protection. It is supplied without a contact block, allowing the required ABB modular contact arrangement to be selected separately. ABB order code 1SFA611202R1006 identifies this exact M2SS3-10B Selector Switch within ABB product group 312001-Pilot Devices (Secrl).

Key Advantages

• Two-position momentary operation provides a simple rotary command interface.
• Spring return from C to B automatically restores the selector to its normal position after release.
• Black short-handle actuator provides compact and convenient rotary operation.

Momentary Rotary Control with Automatic Spring Return

Momentary selector switches are useful where a rotary command should only remain active while the operator deliberately holds the selector in its actuated position. The ABB M2SS3-10B provides two positions with spring return from C to B, automatically restoring the handle to its normal B position after the operator releases it.

This operating principle makes the M2SS3-10B suitable for temporary machine commands, manual control functions and other applications requiring a return-to-normal selector action. ABB's modular pilot-device architecture allows compatible contact blocks to be selected separately according to the electrical switching requirements of the application.

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.
