I will have a look, to see if the inputs and outputs can be coded "in reverse".
Using an electrical analogy is complicated by the fact that the Nodes have Inputs and Outputs, which introduces a "direction" to the data flow.
Electricity could flow in either direction.
The new requested switch is properly called a SPDT, (Single Pole, Double Throw) switch, with one input Pole, and two output terminals.
The existing switch is a "Backward flow" version of this, with two poles and double throw, but the term DPST is not appropriate.
>>>And the code for this node is in the Interfaces.js file.<<<
The SwDPDT switch node which I did is actually a "Backward flow" switch.(?)
So there could be two versions of the SwDPDT switch node.
And two versions of the SwRotary switch node.
