ComfySwitchNode - ComfyUI Built-in Node Documentation

The If/Else Switch node selects between two possible inputs based on a boolean condition.

The If/Else 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. The inputs are lazy, so only the selected branch is evaluated and the other input does not need to be connected.

Inputs

Parameter	Description	Data Type	Required	Range
switch	A boolean condition that determines which input is passed to the output. 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 switch is disabled (false). This input is requested only when switch is false.	MATCH_TYPE	No
on_true	The data to be passed to the output when switch is enabled (true). This input is requested only when switch is true.	MATCH_TYPE	No

Note on Input Requirements: The on_false and on_true inputs are conditionally requested. The node asks for on_true only when switch is true, and asks for on_false only when switch is false. Both inputs must be of the same data type, and that type 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: the value from on_true when switch is true, or the value from on_false when switch is false.	MATCH_TYPE
