The Transistor as Switch Working Model is an educational electronics project designed to help students clearly understand the switching behavior of a transistor. This model demonstrates how a small base current controls a larger collector current to turn an LED load ON and OFF, making the concept easy to visualize and remember. The circuit is neatly printed on a durable board with clearly labeled components such as Base, Collector, Emitter, resistor, LED, and power supply connections. Ideal for Class 9 to 12 students, this project is perfect for school science exhibitions, physics practical’s , STEM learning, and digital electronics demonstrations. It operates on a safe low-voltage DC supply (9V compatible), making it suitable for classrooms, Atal Tinkering Labs, and home learning. This ready-to-use model requires no soldering and supports the Indian NCERT curriculum, helping students connect theory with real-world electronic applications like switches, relays, and logic circuits.
