WebbIn the next tutorial about Bipolar Transistors instead of using the transistor as an amplifying device, we will look at the operation of the transistor in its saturation and cut-off regions when used as a solid-state switch. Bipolar transistor switches are used in many applications to switch a DC current “ON” or “OFF”, from LED’s ... Webb22 maj 2024 · The transistor switch is an "overdriven amplifier". – Circuit fantasist May 22, 2024 at 19:38 It is always an amplifier. It amplifies up to the point it clips on the rail and then that is all it can deliver, making it look like a switch. There is no magic. – old_timer May 22, 2024 at 21:21
