On this slide, the area highlighted in red appears to be bouncing more, but this is actually dynamic noise. The contacts never actually open, but are wavering in the magnetic field producing full closure, then the pressure relaxes on the contacts, but they do not ever actually open. During the relaxation period, the contact resistance increases, the contact resistance becomes less and less with each subsequent cycle. The contacts continue wavering in the gray shaded area. As can be seen, this can continue for almost 2 ms, but should be extinguished after this time. The blue point is where the dynamic contact resistance is actually measured.
