ComfySwitchNode - ComfyUI Built-in Node Documentation

The Switch node selects between two possible inputs based on a boolean condition. When switch is enabled (true), it passes the on_true input through to the output; when disabled (false), it passes on_false. Only the selected branch is evaluated, so the other input does not need to be connected.

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 requests 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. If the selected input is not connected, the node outputs no value.

Outputs

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