The pips were originally controlled by two mechanical clocks located in the Royal Greenwich Observatory that had electrical contacts attached to the pendulums. Two clocks were used in case of a breakdown. These sent a signal each second to the BBC, who converted them to the audible oscillatory signal that is broadcast.
How cool is that? Electrical time signals generated from a mechanical pendulum!
