This is a black DC power jack with an external nut. It has an internal switch which will disconnect the battery power when a DC power adapter is connected so your battery won't drain. Fits standard BOSS-style power supplies with 2.1mm diameter plugs.
One advantage of the external nut model is that you can unscrew it, unscrew your switches, pots and jacks, and completely remove the contents of the enclosure without cutting wires or desoldering.
Available in an economical 10-pack.
