I have seven of the SC-2s under my layout, plus there is one more lurking here somewhere, these are controlling 23 switches (turnouts) and a few cross-overs and the entrances of my reverse loops. I am starting to hook up to lighting and will also hook up some accessories to these. So far I am extremely happy with the control these give. I was hesitant to start using the SC-2, thought them to be unnecessary but now am thankful to another S gauger who recommended them. Now I wouldn't be without them.
