How about 2 test probes on a mechanical bed of nails?
or 2 surface mount test points and a jumper wire with EX hooks?

>Subject: DES/ASSY: 2 pin shunt connector
>
>Greetings, fellow Victor Johansen fans:
>
>We have a new board design which is reaching proto build.
>
>It seems that during the test procedure, it is necessary to short two PTH
>locations momentarily to cause the board to power up in a certain mode.
>
>The designer has brought these two circuit nodes to adjacent 0.040" PTH
>locations at normal 0.100" centers, and labelled the "part" J1.
>
>We typically use a two pin header and a shunt for this sort of option or
>"strapping".
>
>The board design is basically clean, having only a D-sub connector in
>through-hole packaging.
>
>I am resisting the population of this J1 connector, and asking our test
>engineering people to come up with a more novel way of shorting the two
>holes during test.
>
>They seem to think the only way to do it is our old standby header pin, but
>personally I dislike having to hand stuff the things, and from a design
>viewpoint, don't like them protruding up 0.300" off the top of the board
>waiting to rip holes in every ESD bag.
>
>Was hoping someone could point me to some cute "clip" or "plug" which could
>be easily and temporarily plugged into a PTH for only a few seconds. It
>would need to make reliable contact without being held manually in position
>(the test setup will have numerous boards under test in the fixture) but
>should be easily removable by the operator. We would not, of course, ship
>product with the plug, it should be re-useable here.
>
>If anyone has a short, sweet answer please reply to this posting and ignore
>the one from Victor.
