My goal is for a button press to temporarily disrupt the input voltage (120VAC) for a specified interval (around 10 seconds). Ideally, I'd like the interruption of voltage to coincide with the leading edge of the button press; I'm flexible about whether the delay would start at the leading or trailing edge.
I'm getting a headache trying to determine the proper configuration of components to achieve this. I imagine I will need some type of time delay relay in tandem with some type of momentary push button (normally on? normally off?). I've tracked down a few resources that summarize the various timing modes available with TDRs, but nothing seems to offer the functionality I describe above.
I'm a novice tinkerer, and it would not surprise me to learn I'm missing something quite obvious. Any help greatly appreciated!
Edit: If at all possible, I would like to avoid dependence on a second DC source, such as is required in the circuits Samuel and miceuz have proposed. Perhaps there's no getting around this? In lieu of introducing an entirely separate voltage source, would anybody condone splicing into the 120 VAC supply, and then using a transformer to step down to the ~12VDC involved in the 555 / RC timer circuits?
