When switch is closed, capacitor charges to voltage at which uniiunction triggers, then discharges through unijunctior transistor and relay alter time delay determined by RT, which is about 1 sec of delay for each 10K of resistance.- Transistor Manual, Seventh Edition, General Electric Co., 1964, p 320.
