And why did it not work? In order to get any further I think you have to post some schematics, and also the switch configuration. Else we will be guessing for the next year what you are trying to do.I already tried the simple debouncing method with an RC circuit and it didnt work all too well. My next step is a schmitt trigger but then eventually maybe a sophisticated chip to take care of it.
I see, I have been on vacation for 3 weeks. With NO internett so i missed that. As I can see from your circuit B. Morse, the switch are allready debounced.this is the circuit he is working with....

I am almost always in favor of using a microcontroller for things like this, because they are so versatile and take care of so much of the circuit algorithms... and they're adjustable by reprogramming after you've built the circuit. So my suggestion is "yes". I'm partial to AVR, PIC, and MSP430 myself but you can use whatever you like.Thanks Sage. I will start looking into that. As i was thinking more and more though with that circuit, do you think it would be a wise idea to eventually use a micrcontroller to do the roles of the 4017 and the debouncing and drive relays from say an 8051 micro outputs?
That sounds awesome Sage. I dont have any Micro-Controller experience but the thought of programming one for this task really excites me. The fact that such a small chip can do so much excites me and i defenetely want to learn them and look into it. The only issue is the circuit has to be easy to troubleshoot and replace parts of it quick and easy, so i suspect using a microcontroller is much tougher to troubleshoot and replace for an average folk than logic chips..I am almost always in favor of using a microcontroller for things like this, because they are so versatile and take care of so much of the circuit algorithms... and they're adjustable by reprogramming after you've built the circuit.

The drawback may be if you're not experienced with microcontrollers, then they add a new level of complexity.
It can definitely debounce an input with code alone, and it can count and turn on relays in any sequence you want. Add a $0.25 crystal and it can keep real time. Add a TMP100 and it can respond to temperature. ... etc...
Then you should be fine, and it is about time to learn to use a microcontroller, as a versatile tool in your toolbox.and although i dont have micrcontroller expeirence, i am in electrical engineering and have done Assembly and C before and i believe they use the same programming principlas
