Product Description
Large metal 2.1mm DC jack, commonly used on effects pedals. Requires an 11mm hole. More robust than plastic jacks.
Ideally used with center-positive applications. Some applications will require insulating the bushing from the chassis, so that the shell of the plug won't short to ground.
Center Lug = Center Pin
Long Lug = Sleeve/bushing
Tech's notes: "This is not a switching jack."
