Introduction
This circuit contains a timer switch,overload relays,time circuit etc.These are the major devices which are used in it.These devices gives an automatically operation to the motor.This circuit controls the motor with respect to time.Explanation
In this circuit a push button is connected in series.When we pull the button to it's downward position,then the current passes through the circuit and the motor starts running.The timer circuit operates and stars calculating time according to it's setting.when the limited time overs the timer circuit close the circuit and stops the supply of the motor.Circuit Diagram
Uses
This type of control is used in washing machines.ovens,microwaves etc and also in industrial level.
