Touch the metal piece to open, SCR1 turns on, the load is energized to work. Touch the metal piece off, SCR2 turns on, the relay J is energized to work,K is off, the load losses the power, SCR2 turns off, the capacitance discharges to the relay J, it keeps the relay pulling in about 4 seconds, so the circuit action is more accurate. If the load replays to the relay, it can control the large current work load. Friends who are interested, give it a try.
