One of the most fundamental applications of a transistor is using it to control the flow of power to another part of the circuit using it as an electric switch. Driving it in either cutoff or saturation mode, the transistor can create the binary on/off effect of a switch.

Transistor switches are critical circuit-building blocks; they re used to make logic gates, which go on to create microcontrollers, microprocessors, and other integrated circuits. Below are a few example circuits.

to construct a switch using a transistor project

Transistor is a semiconductor device used for switching and amplification of weak signals. This article explains how a transistor work and the working of transistor as a switch. At present, transistors are applied in most of the electronic equipments for switching purposes. Digital ICs, Microcontrollers, etc uses thousands of embedded transistor for switching. The huge electrical networks are also switched by simple transistor switching circuit
(Most of the Power electronics circuits). Here we a ....etc

to set up a common base transistor circuit and to study its input and output characteristics

In electronics, a common base (also known as grounded-base) amplifier is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a current buffer or voltage amplifier.

In this circuit the emitter terminal of the transistor serves as the input, the collector the output, and the base is connected to ground, or common, hence its name. The analogous field-effect transistor circuit is the common gate ampl ....etc

Transistor as a Switch

When used as an AC signal amplifier, the transistors Base biasing voltage is applied in such a way that it always operates within its active region, that is the linear part of the output characteristics curves are used.
However, both the NPN & PNP type bipolar transistors can be made to operate as ON/OFF type solid state switch by biasing the transistors Base terminal differently to that for a signal amplifier.

Solid state switches are one of the main applications for the use of transistor to switch a DC output ....etc
