on video Simple Touch ON\OFF Switch Circuit .With Single Transistor IRFZ44N.

 i will show how can make a touch switch that is gonna replace the normal switch with the help of mosfet transistor.We will make a mosfet button that operates when you touch your finger to the terminal of the transistor.This type of switch can be made with regular transistors but connected in a Darlington pair multiply the number of transistors and amplifying the gain.

The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal–insulator–semiconductor field-effect transistor or MISFET is a term almost synonymous with MOSFET. Another synonym is IGFET for insulated-gate field-effect transistor.
