Shrapnel quick action:Quick-acting contact with self-cleaning mechanism, quick on-off action, more reliable contact; The arc extinguishing performance is good, and the action sends a crisp sound, giving the operator a kind of auditory signal.
Flat press slow motion:Compared with the shrapnel quick action, the conventional translational contact has a larger electrical gap, so the current carrying capacity is larger than that of the shrapnel quick action.
