The component is cheap and easy to work with so it is best suited when choosing a random switching device. How to use 2N Transistor 2N can be used in any general transistor application circuits but for understanding the working let us consider a simple 2N switching circuit as shown below.
In the above circuit we are using 2N as a simple switching device and a small motor as the load. The small button here is for providing the trigger to the transistor and can be removed to leave simple contacts to touch. With the gain of the transistor a simple touch can trigger it. Working Under no interference there will be a positive voltage appearing at the base of the PNP transistor and based on working on PNP transistor having a positive voltage at gate leaves transistor in high resistance state.
Based on the characteristic of a PNP transistor the current needs to flow out of base not in to the base for it to turn ON. So when a positive voltage appears at base only leakage current flows through transistor and all the battery voltage BAT1 appears across it.
As shown in below graph a current of 10mA needs to flow out of base for a flow of mA collector current and switching ON the transistor completely. When the button is pressed the base of the transistor will be connected to the ground and a loop will be formed for the current to flow from the base to the ground.
With this current flow the transistor gets turned ON and a current flows through the collector followed by motor. And so when the button pressed current flows though the motor turning it ON. After the button opened again the base current flow will be cutoff there by turning OFF the motor.
Hence we have used 2N as a simple switching device and in the same way we can use this transistor in all other application circuits.
