The figure is as shown, it is a delay light with digital IC, in figure, it only uses three good inverters of CD4069, the another three invertersare not used; connecting their input terminal to ground,it caneliminate the interferencewith circuit. K adopts JRX-22F、DC12V small middle power electromagnetic relay. The delay time is determined by the charge time constant of R2, C1.
