Ok. I am going to have lots of terms wrong. So bear with me.
I have a momentary switch (S1). I want this momentary switch to control two other momentary switches (S2, S3) in a seperate device. Basically, I want to replace S2 and S3 with something controlled by this circuit.
I prefer to keep S2 and S3 isolated from this circuit, so I'm thinking relays.
Here is the description of how it needs to work.
When S1 is pushed S2 needs to close for a preset amount of time (say 30 seconds).
When S1 is pushed and S2 is closed, S2 timer needs to restart and S3 needs to close for a short duration (fraction of a second).
S2 and S3 share the same common so they do not need to be isolated from each other.
I have been searching for hours and I'm getting lost with all the Latching, debouncing, one-shot stuff. I'm at this point not even sure what to search for.
Any help at all, even if you could just tell me what to look for.
Thanks,
John
