- The trigger causes a pair of electrical contacts to the touch, completing a circuit connected to a specific pin of an integrated circuit (IC).
- The full circuit makes the transmitter to transmit a sequence of electrical impulses set (see how the radio for more details). Each script contains a short sync pulse group, followed by the sequence of pulses.
