Alexa and computer to a plant?

First sorry if there's such a thread already somewhere…

The following: My system has a blade input but only male and I want to connect an Alexa input and my laptop at the same time that I do not have to change the plug all the time…

With the part you can connect to the In / Out connection of your system.

In 1 and 2 the devices.
And so you can simply switch the sources via the buttons.
You can't do both at the same time, but you can switch much more comfortably.
