The flow of current in a circuit can be managed using a switch such as a bipolar junction transistor (BJT). When employed in this manner, the BJT can control the flow of current to a load since it is either totally "on" (saturated) or fully "off" (cut-off). A BJT switch can be used in light control circuits to turn on or off a light source in response to an input signal. In this instance, the signal from a sensor or other input device operates the BJT as a switch.
