SEL 3 CRET
Three-position centre-return selector
A centre-return selector returns from both outer positions to its documented central rest position.

What it represents
The return-from-both selector form identifies an operator returning from either outer position to its documented rest position. The middle contact state and both momentary command states require explicit annotations.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Read release behaviour for each outer command.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- Identify rest position
- State outer-command actions
- Reference contact schedule
A distinction that matters
Return to centre is an operator characteristic; centre off is an electrical contact condition.
