Best way to switch between Signals?

[Smart]

Hello,

what is the best way to switch between different input signals?
I attached my solution, but I believe there is a smarter way.

Best!

Hi,

As a beginner, I also tried to find a signal switch, but failed. So I used the expression block(as below drawing) to switch two signals, for your reference.

I also believe there must be smarter ways that it.
