| I've used this home- made unit several times with no problems. The relay is a small reed relay. The caps are tantalum or electrolytic, back to back. The "A" leads go to the equivalent hold leads on a key set and use the other two wires in the mounting cord (Yello/Black). The units i made were put into tiny utility-boxes. |
