Robo India in this tutorial explains how to use transistor as switch. 1. Introduction: Transistor can be used for many operations eg. amplification, switching etc. Here in this tutorial transistor is being used a switch. A transistor has got three terminals Collector, Base and Emitter. If Base is trigged with some voltage, It allows current

Robo India in this tutorial explains how a push button works. This is used as an input device. That takes input from user. This is also termed as push to on switch.  1. Introduction: Push button is a switch which connects its terminal if it pressed. As the button is released terminal gets disconnected. Thus
