1SFA619211R1027 ABB C3SS2-10U-20 Compact 3-Position Momentary Selector Switch 2NO

Why Choose the ABB C3SS2-10U-20 Compact Selector Switch?

The ABB C3SS2-10U-20 is a compact and reliable 3-position momentary selector switch designed for industrial machinery, control panels and automation systems. Identified by ABB order code 1SFA619211R1027, it forms part of the ABB Compact Pushbuttons range and combines the selector operator and contact functions in an efficient all-in-one design.

This selector switch features a grey short-handle actuator with a black plastic bezel and three operating positions. Its spring-return action returns the handle to the centre B position, making it particularly suitable for temporary left/right commands, directional control and other industrial functions where the selector should automatically return to its normal centre position after release.

The C3SS2-10U-20 incorporates two normally open (2NO) contacts and is non-illuminated. Designed for standard 22 mm panel mounting, it provides IP66 front protection and screw-terminal electrical connections, making it a practical choice for demanding industrial operator-control applications.

Key Advantages

• Compact 3-position momentary selector switch for industrial control applications.

Reliable Three-Position Momentary Control for Industrial Machinery

Three-position momentary selector switches provide operators with a convenient method of issuing temporary control commands in either direction from a defined centre position. The ABB C3SS2-10U-20 uses a spring-return mechanism that returns the selector to position B after operation, allowing the switch to provide temporary commands without remaining latched in the actuated position.

The ABB Compact range is designed for machine builders, panel builders and industrial automation engineers requiring efficient operator controls with straightforward installation. The C3SS2-10U-20 combines its three-position spring-return selector mechanism, integrated 2NO contacts, grey short handle and black plastic bezel in a compact assembly suitable for standard 22 mm control-panel openings.
