Hello,

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

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.
