Crutschow posted an LTSpice simulation in another thread that used a voltage controlled switch. After struggling with getting this to work in another sim, I was wondering if he/someone could provide some tips into using this technique.

I ended up finding models for SPST, SPDT and DPDT switches on the Yahoo LTSpice group which worked, but I'd like to understand how the technique Crutschow used works.
