Switches in Electronics
T his time we shall be dealing with the practical application of the basic transistors; be it BJT or MOSFET each of these act as a switch in vivid applications. By the not just a switch!! These are high performance switches which work at very high switching speeds...may be in fraction of secs or milli secs! Now, What do you understand by the term Switch?? Definition: A switch is a device for making and breaking the connection in an electric circuit. Since the basic definition is lucid now, lets go into further details. Switches can be of two types : Electromechanical switch Electronic switch Electromechanical Switch: The switches that you use in your homes for day-to-day purposes like turning on your fans and lights or the motorized toy cars we used to play with. The fig below shows the inside out diagram of a basic level electromechanical switch. As we are more concerned with the electronics side, we shall not go in depths with this electromechanical switch. ...
