ComfyUI-IterSwitch

A set of dynamic switch nodes for ComfyUI, designed to simplify complex workflows by allowing flexible, iterative input selection. These nodes provide dynamic connection management and intelligent fallback logic.

Key Features

Dynamic Inputs: Automatically resizes the number of input connections based on the input_count widget.

Smart Fallback:

With the use_last_input option enabled, the node can search backwards from the current index to find the nearest valid (connected) input, ensuring a result is always returned.

Type Support:

Includes switches for Text, Conditioning, CLIP, Image, Model, and Float types.

Example Usage: Iter_TextSwitch

The Iter_TextSwitch node allows you to combine a base string with one of many dynamically connected inputs.

1. Basic Connection The node takes an add_text input (base string) and allows you to dynamically define multiple text inputs. You can select the specific input using output_index. Example using waiIllustrious v16
2. Fallback Logic When use_last_input is enabled, the node becomes more robust. If your current output_index points to a disconnected or empty input, the node will automatically search backwards through your inputs until it finds the most recent valid (connected) string. Example using waiIllustrious v16
3. Iterative Workflow By using the output_index, you can easily integrate this node into iterative loops, ensuring that your text prompts are dynamically selected or concatenated based on your workflow state. Example using waiIllustrious v16
