As the diagram shows it is a touch type delay lamp circuit using music IC(CIC8251). It makes use of a music integrated circuit memory function to realize the control delay. The delay time is 1min. The circuit can use common KD-9300serie music IC. But generally this serie music IC are without external oscillation resistance. The circuit delay time is about 20s fixed by chip circuit.
