Tube Light Starter Internal Circuit Diagram and Detailed Working Analysis

Sir,

I want to know the internal  circuit diagram and working analysis of tube light starter 

Below I have attached the image 

When the switch is pressed current cannot pass through the tube initially because the gas inside it is not ionized and hence the tube light circuit behaves as open circuit. Once the gas is ionized, it will provide a conduction path for the current to flow. In order to ionize the gas, an initial high current is required for a short period across the filaments of the main tube. That is what a starter does. A starter initially provides a path to complete the circuit and once tube light starts the current flows through the ionized gas in the main tube.
