![]() If you haven’t noticed by now, the source and drain connections on a JFET look identical on the schematic symbol. Remembering that the controlled current in a JFET flows between source and drain, we substitute the source and drain connections of a JFET for the two ends of the switch in the above circuit: ![]() ![]() Let’s begin our investigation of the JFET as a switch with our familiar switch/lamp circuit: Like its bipolar cousin, the field-effect transistor may be used as an on/off switch controlling electrical power to a load.
