Why Choose the ABB C3SS7-10R-20 Compact Selector Switch?
The ABB C3SS7-10R-20 is a compact three-position maintained/momentary selector switch designed for operator control in industrial machinery, electrical control panels and automation systems. Part of ABB's Compact pilot-device range, it combines the selector operator and electrical contacts in a space-efficient complete assembly.
This selector switch features a red short-handle actuator, non-illuminated construction and a black plastic bezel. Its operating sequence provides spring return from position A to B while position C is maintained, enabling both momentary and maintained commands from a single three-position operator.
The C3SS7-10R-20 incorporates 2 normally open (2 NO) contacts and is designed for standard 22 mm panel mounting. With a compact 30 × 30 × 72 mm form factor and ABB order code 1SFA619216R1021, it provides a practical solution for machine-mode, directional and process-control functions.
Key Advantages
- Combines maintained and momentary operation within one three-position selector switch.
- Spring return from A to B supports temporary commands from one side of the selector.
- Maintained C position supports a persistent operator-selected control state.
- Integrated 2 normally open (2 NO) contacts provide dual switching capability.
- Red short-handle actuator provides clear identification and convenient operation.
- Standard 22 mm mounting format supports integration into industrial control panels.

Combined Maintained and Momentary Three-Position Control
The ABB C3SS7-10R-20 provides a specialised three-position operating sequence in which position A springs back to centre position B, while position C is maintained. This allows one side of the selector to be used for a temporary operator command while the other can establish a persistent selected state.
Its integrated 2 NO contacts provide two normally open switching paths within the compact assembly. Combined with its red short handle, black plastic bezel, 22 mm mounting format and non-illuminated design, the C3SS7-10R-20 is well suited to machinery controls requiring both momentary and maintained selector functions from one operator.
Typical Applications
- Industrial machinery control panels.
