1SFA619211R3021 ABB C3SS2-30R-20 Compact 3-Position Spring-Return Selector Switch 2NO

Why Choose the ABB C3SS2-30R-20 Compact Selector Switch?

The ABB C3SS2-30R-20 is a compact and robust 3-position spring-return selector switch designed for industrial machinery, control panels and automation systems. Identified by ABB order code 1SFA619211R3021, 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 red short-handle actuator with a durable chrome metal bezel and three A-B-C operating positions. Its momentary mechanism provides spring return to the centre B position, making it particularly suitable for temporary directional commands and machine-control functions where the selector should automatically return to its normal centre position after release.

The C3SS2-30R-20 incorporates two normally open (2NO) contacts with no normally closed contacts and is non-illuminated. Designed for standard 22 mm panel mounting, its compact construction and spring-return operation provide a practical operator-control solution for demanding industrial applications.

Key Advantages

• Compact 3-position spring-return selector switch for industrial control applications.
• Spring return to centre position B automatically restores the selector after release.
• Highly visible red short-handle actuator provides straightforward manual operation.
• Durable chrome metal bezel for demanding control-panel installations.

Reliable Three-Position Momentary Control for Industrial Machinery

Three-position spring-return selector switches provide operators with a convenient method of issuing temporary commands in either direction from a defined centre position. The ABB C3SS2-30R-20 uses A, B and C positions with automatic return to B, allowing the operator to select either outer position temporarily before the short handle returns to its normal centre position when released.

The ABB Compact range is designed for machine builders, panel builders and industrial automation engineers requiring efficient operator controls with straightforward installation. The C3SS2-30R-20 combines its three-position spring-return selector mechanism, integrated 2NO contacts, red short handle and chrome metal bezel in a compact assembly suitable for standard 22 mm control-panel openings.
