A drive train is for a displaceable contact on a breaker contact
arrangement in an electrical power breaker. A coupling element
displaceable against a stop and arranged between the moveable contact and
corresponding drive element is provided with an anti-bounce device,
including a catch element and a counter piece. The catch element which may
be swung into a catch position as a result of the inertia exerted on the
centre of gravity thereof, when the coupling element strikes the stop,
includes a working surface extending in the pivoting direction to forma
momentary working connection with the counter piece. A retaining spring is
additionally provided on the catch element to guarantee that a rebounding
of the coupling element into the position corresponding to the close state
of the breaker contact arrangement does not occur.
