Sometimes a circuit needs to be unpowered when the simulation starts, for example due to convergence errors or for an oscillator to start normally. Switches work, but I keep leaving them in the wrong state. I've been wanting a circuit to automatically delay switch-on, but generally don't want to bother when I'm already working on a circuit. They can be a pain to set up. I tried a relay-based one yesterday; it seemed simple but didn't want to work reliably at the simulation speed I needed. I used a FET-based one instead, and had to put up with no current dots in my main circuit. This circuit I think will be free of all these faults. The only thing to really remember is the delay in the logic train.
