A variation on
the connector idea: use an insulation-displacement type
connector (the kind that you mount onto a flat cable assembly) without
the cable. Just snap on the cover over the i-d pins and you have a
fully insulated assembly with the pins acting as spring clamps for the
jumper pins.
That's not terribly useful when you have only one or two positions to
protect, is it?
Following the idea however you can use a wire-to-board connector housing
like from Harwin M20 series with just empty contacts inserted. They are
widely available and start from 1x1 even.
