The quartz crystal, cut and finished in the shape of a tuning fork, is responsible for delivering a intervallic voltage, drawn from its piezoelectric frequency, to the circuit, but how the circuit chooses to use that voltage is a different matter. The load, or drain, on the battery increases with the introduction of mechanical friction. […]
