When the level is lower than b, V is disconnected and K doesn't work. Its K2 is disconnected and K1 is connected. M begins to feed water. When the level reaches A, +12V voltage is put on V, making V connected. K begins to work. Its K is disconnected and K2 is connected. M stops working. When the level is lower than B, V is disconntected and K is released. K2 is disconnected and K1 is connected. KM is connected and M begins to work again. The circuit works like this and feed water automatically.
