Erik,

>>In other words: I tell you that it works, but keep vital information (CTS must be set and not toggle) from you.

I was just telling Sanjeev to look for other ways of doing instead of ICs. I mentioned transistorised circuit works (or worked) for me and I never explained how the ckt works. I suggested Sanjeev to search the net and the "for example" site referred was a hint for him what to expect and I did not say it is "the" ckt. CTS issue - since you asked I answered. I don't see where I misled anybody. If it has given that impression I am sorry.

>>Does everybody see how dangerous this kind of "help" is?

Erik, I have high regards for your experience and knowledge. You have helped me in the past on my posts. Thank you for that. I was not trying to prove a point with you but explain myself. Anyway, I will "shut up" and let the knowledgeable talk.

regards,
