Connector suggestions for swapping DCC power from one controller between layouts

[potatan]

I have an NCE PowerCab. The power-out is two small terminal screws. I have (almost) two layouts that I would want to use the controller with, so I'm looking for suggestions for a plug and socket to allow easily swapping the PowerCab from one layout to another. At a guess I need something with no more than two connections, +ve and -ve, but I may be overlooking a future use case that hasn't occurred to me.

So the plug would be permanently wired to the PowerCab screw terminals, then each layout will have a socket that I can plug the PowerCab into in order to play with that layout.

something like this?

"screw terminal barrel connector"

you can also get panel mount versions of the socket, and if you don't want the screw terminals there are soldered versions with a suitable boot

potential drawback is mistaking it for a power connector, it could be better to use something like

which you then don't use for anything else (these can be had in two connections as well)

Barrel connector looks simple enough if that's all that's required, just need a threaded one that can be pushed through a bit of 9mm plywood and secured with a locknut. Thanks

I like Speakon connectors, very cheap and industrial strength connectors used for speakers on stage, so they have to be tuff:-

They are 4-pole so you can have auxiliary power as well as track power and nice big terminals to take big wires. They re designed to work with 2-core and 4-core speaker wire to make things neat.
