# switch

This block is part of the [`field validation`](https://docs.rual.nl/block-types/field%20validation) group and was last modified in core [`v12.0.5`](https://docs.rual.nl/core-versions/120005).

Returns a given validation based on the connected expression

- expression required `value` The expression to be evaluated

- Default `fieldvalidation` The default validation to be returned if no match was found

- fieldvalidation `fieldvalidation`

- match `condition` Returns true in case a match was found.

A typical wiring for [switch](https://docs.rual.nl/block-types/field%2520validation/fieldvalidation_switch): [value](https://docs.rual.nl/block-types/value/value_default) feeds the `value` pin; the `fieldvalidation` out pin feeds [radio](https://docs.rual.nl/block-types/Component%2520UI/component_radio).
