Transistor Switch ON/OFF Terminals
A transistor acts as an electronic switch by controlling current flow between two main terminals, based on a signal applied to a third control terminal.
Switching Action Explained
- ON State: The transistor conducts current, allowing flow between the Collector and Emitter. It functions like a closed switch.
- OFF State: The transistor blocks current flow between the Collector and Emitter. It functions like an open switch.
The Base terminal receives the control signal that determines the ON or OFF state.
Key Terminals for Switching
The essential terminals defining the switching action (the path that opens or closes) are the Collector and the Emitter.
