The way the switch works is that the pins screw into the copper discs (moon pieces) and squeeze them tight against the nylon pieces with the switch prongs in between thus making the switch contact from one side to the other. When/if you take the sector apart, note the prong impressions in the nylon. Screwing the pins in will only serve to increase the connectivity of the circuit unless somehow the switch is incorrectly assembled or the switch prongs are broken. I both these cases and seeing that the unit is a new purchase, I would recommend getting warranty service. Having a multimeter would remove so much of the guess work and you could test the switch sector isolated from the other parts.
Also, from personal experience, Witch kept killing addies within a short amount of usage and had a 1 milimeter or so gap between the switch sector and the adapter sector. We found that the adapter pins were just slightly low. I found some small hard plastic pieces and padded my vice grips and sqeezed the adapters very carefully until the gap was reduced and the center pin contacted the addy more solidly. A note on this is that over squeezing will cause the pin to get to far away from the switch sector and posibly create a continuity problem there ... I happen to have some tiny washers that fill this gap. A weak contact in many cases is worse than a broken contact in that it allows uncontrolled spikes in power flow.
Anyway, Isaac has always been good help to us and does back his stuff, so worst case, send it back to him and give him the chance to make it right for you.
