Before revision: Transistor as a switch BJT used as an electronic switch in grounded-emitter configuration Transistors are commonly used in digital circuits as electronic switches which can be either in an "on" or "off" state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates.
