What does the tristable switch (tritch) do?
ANSWER. Tristable switches are part of some color adapters, including Colordaptor. Such a switch is really a flip-flop with an extra stage. When such circuits toggle (switch), either one stage comes on, or two stages come on. If you invert the circuit output, one stage at a time passes current. (What you really have is a basic shift register.) Anyway, here’s how Colordaptor uses its three-way switch…
