Any Switch Select

ComfyUI workflows get big, and the way you keep them manageable is by not building ten separate graphs. Any Switch Select is the multiplexer: one select integer picks one of up to ten inputs and passes it through. Flip the integer, and a completely different subgraph feeds your next node - same wire, different data.

Where this shines over a manual rewire: lazy evaluation. Only the selected input branch actually runs. The other nine inputs are never computed. That's not a performance nicety - it's the difference between a switch that loads one model and a "switch" that loads ten and picks the result. In a world where "switch" nodes sometimes still compute everything, lazy selection is the reason to reach for this one.

How it works

• select - integer, 1–10, maps to input_1 through input_10. Out-of-range values get clamped rather than erroring.
• input_1…input_10 - any type (*), all optional.
• output - the chosen input's value.
• select (the output port) - the effective clamped value actually used for routing. Feed it downstream if you want to know what really got selected.

The type-agnostic * ports mean you can switch between images, models, prompts, conditioning - anything. The lazy check runs before execution: if the selected input isn't connected, you get None immediately instead of hanging the graph waiting for a dead branch.

Where it fits

The patterns that click with it:

• Mode multiplexer - one select routes between "portrait / landscape / square" resize branches, or "fast / quality" samplers.
• Model or LoRA picker - select between alternative resources without unloading anything.
• Presence-based routing - combine with the pack's Any Empty Int to derive select from whether some earlier input exists, turning a manual switch into an automatic fallback.

Siblings worth knowing: Any Switch Bool is the two-way boolean version, and Multi Switch Select routes one input to multiple outputs. This one is the classic "pick one of N" case.

Common issues

• Getting None out - select points at an input that isn't connected. Check the number on the select input matches a wired port.
• Expecting all branches to run - they don't, and that's the feature. If you need everything computed (say, for side effects), this isn't the node.
• Index confusion - it's 1-based. select=0 clamps to 1, not to a "none" option.

For the price of learning one integer input, you get to keep a multi-mode workflow in a single file instead of maintaining five copies. That's the real value.
