During the swing of the pendulum through the zero position a platinum contact is closed and gives the magnet at the end of the pendulum an impulse through the magnetic coil. The swing of the pendulum moves with the aid of a small lever a ratchet wheel that in turn moves the movement of the clock.
The timekeeping of these electric clocks is very much higher than the one of the usual mechanical clocks with a mechanical escapement. Most important is the correct function of the contact.
