UJT is an abbreviation for (Unijunction Transistor) the electronic component that is at the heart of a simple timing circuit. A UJT timer is a circuit used in an electonic system to deliver a specific time. For instance, a 30 second UJT timer might be used to turn on a Green traffic signal for 30 seconds, then turn off. UJT is a specifically cheap way of doing this type of timed signal. Timers using UJTs have largely be superseded by timers based on a 555 integrated circuit.
