ComfySwitchNode - ComfyUI Built-in Node Documentation

The Switch node selects between two possible inputs based on a boolean condition. It outputs the on_true input when the switch is enabled, and the on_false input when the switch is disabled. Only the selected branch is evaluated, so the other input is not required. This allows you to create conditional logic and choose different data paths in your workflow.

Inputs

Parameter	Description	Data Type	Required
`switch`	A boolean condition that determines which input to pass through. When enabled (true), the `on_true` input is selected. When disabled (false), the `on_false` input is selected.	BOOLEAN	Yes
`on_false`	The data to be passed to the output when the `switch` is disabled (false). This input is only required when the `switch` is false.	MATCH_TYPE	No
`on_true`	The data to be passed to the output when the `switch` is enabled (true). This input is only required when the `switch` is true.	MATCH_TYPE	No

Note on Input Requirements: The on_false and on_true inputs are conditionally required. The node will request the on_true input only when the switch is true, and the on_false input only when the switch is false. Both inputs must be of the same data type and must match the output data type.

Outputs

Output Name	Description	Data Type
`output`	The selected data. This will be the value from the `on_true` input if the `switch` is true, or the value from the `on_false` input if the `switch` is false.	MATCH_TYPE
