This is a well-known integrated circuit based on NE555. Two buttons PB1 and PB2 are connected to pins 4 and 2 for stopping and starting the timer, respectively.
Timer made by NE555
This timing value is determined by the values ​​of RV1 and C1. By increasing the value of these two components, you will get more time. The output signal of pin 3 of NE555 drives the relay through transistor 9013. Diode D2 protects the circuit from any mis-connected input power.
Timing control can be achieved by connecting the load you want to control to the normally open end of the relay. For example, controlling the timing of the electric fan.
