Electronics Forum / CAD / September 2005

I've spent a few hours over the last couple of days trying to design a
realistic and easy-to-handle simulation for break-before-make toggle
switches. But I imagine this is re-inventing the wheel, as there must
be well-established techniques. I'm using Circuitmaker, but I assume
the principles must be similar in other programs.

My approach so far (to the more complex case of a SPDT switch) has
been to use two VCSs, a triangle wave input (inverted before applying
to the 2nd VCS), and altering the respective VCS's Threshold values to
get the 'break-before-make' delay. But I expect I'm making heavy
weather of it, and would be grateful for shared techniques please.
