Connect 2/3 laptops together?

In order to switch between laptops at the moment, I have to change a USB hub and the HDMI cable so that I can see another laptop on my main screen and use the keyboard / mouse / headset.

Is there any convenient way to do this that somehow connects the laptops to one another and either changes the "active" laptop at the push of a button or even connects everyone as if they were one device?

So in the end the following 2 desired options:

-Laptop 1 with main screen 1 and peripheral devices 1 is active. At the push of a button and laptop 2 becomes active with main screen 1 and peripheral devices 1

- Laptop 1 with main screen 1 and peripheral devices 1 and laptop 2 and laptop 3 are active and can be changed as with multiple screens

The key word here is a KVM switch.

Mostly used on servers. With this you can switch between several Pc / Laptops. Usually also with USB.

But these things are not cheap
