Hello and thank you!
I am looking to create a transistor delay circuit to replace a relay delay device. Hopefully the attached image gives all the necessary information for the idea. I am looking for an approximate 1 second delay, 2 seconds is fine also. A quick reset condition is appreciated also. This "delay switch" will power a bank of relays consuming up to approx 2W in some circumstances and a low of about 1.2W in others. Basically I hope to have it start it's cycle when the mains power is on and have it "turn off" when the mains power is switched off. In the attached image as an option I would like to possibly operate the "delay switch" by some means, showing a ground signal controlled operation. If it is easier or better, controlling this "switch" using either the positive or negative rail is fine as well. Word on the street is that a JFET circuit is the way to go in this instance. Hopefully I haven't missed anything
Thank you in advance for all the help!!
