Hi Barry,

Attached is a draft node, SwSPDT_DRAFT.js.
It has one input, and two outputs.
It may be copied to the nodeeditor Extensions folder, and when MoI & Nodeeditor are re-opened, the node will appear in the Widgets menu.

The Bezier curved connection indicator was modified by trial and error, based upon some Bezier information.
Control point 1 and cp2 "x" values were swapped, and some Y and 10 values were interchanged.
Due to limited Bezier understanding, the changes seem a bit "mysterious".
There is a link in the SwDPDT.js file to some Bezier/canvas information.
...Got some help from Wayne a few years ago...
The non-switch selected Terminal is "floating"?

The main problem is that the Output switched away from should perhaps be reset with some default value?
What should the default value be? It must be numeric?
Display has a "NoInput" default value, but does not reset to NoInput.
Is there some numeric "null" value?

The SwSPDT_Draft node may have a Const node input.
Each Output can be wired to an Infos > Display node.

Testing was rudimentary...
Someone who knows what they are doing should check it out...

Anyway, had some fun.
Cloned 256mb PCIe 4.0 NVMe M.2 SSD with Samsung software, to new Samsung 990PRO, 2TB, which replaced the old boot SSD on Dell computer. It was easy using a portable NVMe case to USB adapter, (temporary for the cloning). (Windows 11)

This SwSPDT_Draft node contains several errors.
The errors are corrected in WN's switchRevers.js file (RevSwitch)
