Easiest and cheap to make a voltage regulator using a few components. With two push switches, you can easily control the power of output voltage. Sounds looks good, yes it is possible to build with a few electronics components. These are cheaply available in any electronics shop.
It is also known as the push-button voltage regulator. With the presence of two push switches, you can increase or decrease the power in the output section. Turn on the circuit and press any button and see the difference in the output. More clearly connect a DC light in output. Then press those buttons and realize the working of the circuit.
Circuit Diagram
connect any load working with 12v ( bulb ) to check the circuit. if you are pressing the SW1 button then the circuit will provide more current through the IRF 3205 mosfet. pressing the second switches h of SW2 will reduces the passage of current through the mosfet.
