One of the reasons the SmartPlug can have so much more metal to metal contact surface area between the male pins and the female socket is because this is a single-action device. This means it only has to INSERT but does not have to TWIST as well. The shaping of the female socket to accept the TWISTING results in considerably less surface area contact.


The other reason there can be more contact area, is because the pins are FLAT not curved. This makes it much easier for spring tension to create a longer & wider mating area, as you'll see below.


NOTE: At this point in time SmartPlugs are for the boat end only. This is the end that sees the most abuse and a 50% fix is better than no fix at all.. SmartPlug is awaiting approvals for the dock pedestal end, a long and arduous process, and once they do they will have dock pedestal products available.
