Timers were used in many applications in our day to day life.One can see the timers in washing machines,micro ovens etc. These devices uses timer to switch the loads for particular amount of time.Traditionally, various loads would have been manually controlled, i.e., the operator would turn ON the loads and after desired conditions met, the loads again would have been turned off by the operator.
