The structural element of the tube light is an airtight glass tube which is commonly called a sealed glass tube. This tube is airtight. The tube fills with a small amount of mercury. Also contains an inert gas (usually argon). The tube inside is also coated with phosphorus. That’s why it looks white. There are two electrodes at both ends of the tube which can create an electric field between them. These two electrodes are again connected to an electrical circuit. Electrical This circuit usually consists of a starter switch and ballast. This circuit is connected to our AC supply. The difference between ordinary incandescent bulbs and fluorescent bulbs (which we call tube lights) is the process of activating or exciting the atoms. In normal bulbs, the atoms are activated by heating. And in fluorescent bulbs, this is done through accelerated chemical reactions.

An SPST (Single Pole Single Throw) Switch is a Switch That only Has a Single Input and can Connect Only to one Output. This means it Only Has one Input Terminal and Only one Output Terminal. A Switch is a Mechanical or Controlling Device That Changes the Flow of Current Direction or Interrupts the Flow of Current Within a Circuit. Single Pole Single Throws (SPST) is Perfect for on-off switching. When the SPST is closed, the Circuit is Closed and the light from the lamp switches on. When The Single Pole Single Throw (SPST) is then opened, the light from the lamp goes out and the Circuit is off.
