When the level is low, ac voltage of 220V will provide the circuit with 10V dc voltage. VL is illuminated. When S2 is disconnected, V1 is disconnected. K2-1 and K2-2 are connected, and the motor begins to feed water. When the level reaches the highest level, S2 is connected, and V1 is connected. K1 K2 are released. M stops working. When the level is between the lowest and the highest, S2 is disconnected. When the level reaches the lowest, the circuit begins to work again, and M begins to feed water.
