I need some help here on a timing circuit, I tried following the attached diagram with some additional relays but for some reason I cannot get it to work.
This is what I need:
A timing circuit so when I push a momentary switch, I have a ground output for 3 seconds.
Now to go into a little more detail. I have two 12v inputs to switch the relays. I have 1 wire that needs the 3 second ground. If I have 12v on BOTH inputs, I need a momentary push of the button (momentary ground from pushbutton) to start the 3 second ground output. If I do not have 12v on BOTH inputs, I need the wire to passthrough to another wire with no 3 second ground output.
All these wires are low current signal wires.
Any help would be highly appreciated!! Thanks!
