🦊 RS Any Switch

Most of ComfyUI's switch nodes are picky about types - an image switch won't pass a model, and a model switch is useless for text. 🦊 RS Any Switch (RSAnySwitch) doesn't care. It accepts anything: IMAGE, LATENT, MODEL, AUDIO, VIDEO, STRING. Up to twenty inputs, one active at a time, switched with a visual ON/OFF toggle per input. If you've ever rebuilt a workflow because you wanted to A/B two checkpoints or compare three upscalers, this is the node that stops that.

How it works

The backend is almost embarrassingly simple - which is the point. It declares twenty input_N slots of type * plus a hidden active_input string, and on execution returns whichever connected input is named active (falling back to the first non-empty one). The real work happens in the frontend: inputs appear automatically as you connect wires, get numbered and labeled with the source node's name, and each gets a toggle switch. Turning one on switches the others off. Disconnect a wire and its slot disappears, so a half-empty switch doesn't clutter the graph.

Because it's type-agnostic, it's the rare switch that works anywhere in a graph - in front of a KSampler for seed/model A/B, in front of a SaveImage for image selection, or in front of a CLIPTextEncode for prompt switching.

Inputs that matter

• input_1 … input_20 - all optional, all *. Connect whatever you want to switch between. The first connection becomes active automatically.
• active_input - a hidden string ("input_1" by default) the UI writes to; you don't normally touch it directly. Selection state is saved with the workflow, so your choice survives a reload.

Output: output - passes through whatever the active input is, unchanged.

How to install

Part of ComfyUI_RaykoStudio:

cd ComfyUI/custom_nodes
git clone https://github.com/Raykosan/ComfyUI_RaykoStudio.git

Restart ComfyUI, or install via ComfyUI Manager by searching "ComfyUI_RaykoStudio". No extra dependencies beyond the pack's standard requirements.

Common issues

• The right input isn't active. Click the toggle on the one you want - the active slot shows a green-bordered status bar, and only one can be ON.
• Output is None / nothing flows. If active_input names a slot that's now disconnected, it falls back to the first connected input. If nothing's connected at all, you get None, which will error downstream - that's the expected failure mode for a passthrough switch.
• Stale labels. Node names are shown truncated to 20 chars; if you renamed something, hit the "UPDATE NAME" button.

The honest take: for serious A/B testing there are fancier routers (Impact Pack has a whole family), and if you're switching models you might prefer the pack's own RaykoModelsLoader presets. But as a dead-simple, any-type A/B switch, this is one of the easier ones to throw into a workflow without reading a manual.
