The figure is as shown, it is a acousto-optic control stair delay switch which adopts LM324 operational amplifier, it adopts two-wire system connection, it can replace the ordinary light switch directly, it is not needed to change the indoor original wiring. In figure, the operational amplifier A1~A4 which is connected into four voltage comparator can use a single power supply four operational amplifier IC LM324, theother components are as shown, there is no special requirements.
