[SOLVED] Solving an Audio Interface Puzzle

[Mosteeze]

I currently have a set of studio monitors and a pair of headphones hooked up to a Focusrite Scarlett Solo (2nd Gen) audio interface.
(PC > Interface > speakers+headphones)

The issue here is, sound comes out of both the headphones and speakers simultaneously.
I have to unplug the speakers' RCA cables from the back of the interface every time I want to record to only have sound come through the headphones.
The problem worsens as I want to add a Logitech Wireless Bluetooth Reciever to the speakers
(preferably to the interface(possible?) so I could hear BT sound through the headphones too, it would be a plus but not important. That's a different issue though.)

Mainly, I just want some piece of hardware connected to my audio interface that will allow me to switch between headphones/speakers/both with a push of a button.

I've read many posts on similar issues and most just suggest either purchasing a more expensive audio interface with this capability built in,
purchasing a Monitor Controller, or an AV Switcher.

But I'm confused about the connections, as my headphones plug into the interface itself via headphone jack and the interface only has 1 RCA connection on the back.
Also, I don't want to have to use an alternative where I'm not getting the benefits of the audio interface through 1 output, as that would make the interface pointless.

If anyone can help clear up some of this or give me some info/advice, I'd greatly appreciate it.

Thanks in advance.

TL;DR
I want to be able to switch between headphones and studio monitors on an audio interface that doesn't have the capability of switching itself.

You can simply stick a on/off or a source selector switch between the interface and the speaker wires https://www.amazon.com/dp/B08JGWHBH...uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl

JDS Labs has a device also https://jdslabs.com/product/ol-switcher/

The Mackie Big Knob is a great device but a bit high end for what you are doing.

None of this will have to touch the headphones really you just need to connect it to the speakers and just toggle the switch to off or to an empty connection.

Something like a Micca OriGen to replace the Focusrite also, has a selector switch https://www.amazon.com/Micca-OriGen-G2-Resolution-Preamplifier/dp/B01N14SY65
