- You can make them yourself even cheaper... There is an article in a recent
- issue of Radio Electronics that gives about a dozen different circuits for
- solid state relays and the like. Look in your library for solid state relay
- related articles and I am sure this article will pop up. The basic circuit
- is quite simple and sould not cost more that $2 depending, of course, on the
- current rating of the Triac used.

- If you can't find the article let me know and I will try to remember to look
- for that issue of Radio Electronics when I am at home...
