1SFA619211R3026 ABB C3SS2-30B-20 Compact 3-Position Momentary Selector Switch 2NO

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

The ABB C3SS2-30B-20 is a compact and robust 3-position momentary selector switch designed for industrial machinery, control panels and automation systems. Identified by ABB order code 1SFA619211R3026, 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 black short-handle actuator with a durable chrome metal bezel and three A-B-C operating positions. Its momentary mechanism provides spring return from A and C 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 C3SS2-30B-20 incorporates two normally open (2NO) contacts with no normally closed contacts and is non-illuminated. Designed for standard 22 mm panel mounting, it provides IP66, IP67 and IP69K front protection, a 300 V rated insulation voltage and screw-terminal connections for dependable industrial control applications.

Key Advantages

• Compact 3-position momentary selector switch for industrial control applications.
• Spring return from A and C to centre position B automatically restores the selector after release.

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 C3SS2-30B-20 uses A, B and C positions with spring return from A and C to B, allowing either outer position to issue a temporary command before the selector automatically 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 C3SS2-30B-20 combines its three-position spring-return selector mechanism, integrated 2NO contacts, black short handle and chrome metal bezel in a compact assembly suitable for standard 22 mm control-panel openings.
