Easy question about “Clicks“

I have got a button where I switch over a Matrix Object Signal A) or Signal B), I was not wondering that this switch produces “clicks“, but I don't know how I could insert the “Line“ Object correctly, because I don't know which argument I should give him. The arguments usally are “from, to, in", but the Singal is a Sinus. Should I use a variable argument like “$".

Thank you very much in advance
