Switchcraft plugs do not have that problem, the center pin is slightly
recessed.

I have managed to blow fuses in my battery power supply by shorting
the unconnected 2.1mm center female power plug. On some of these
connectors, the center female section protrudes out of the end of the
plug. This piece of the plug is easy to short to ground. Elecraft
recommends connecting the power plug to the KX3 before turning on the
power supply, which is good advice. If your power supply is always on,
like my batteries, be really careful about shorts and carry spare fuses.
There may be a blown fuse in your power supply.
