FGG.0B Quick Connect 4 Pin Plug - 9mm Outer Diameter

If you want the look and feel of aeronautical style quick-release connectors, this FGG.0B 4-pin Plug  is an elegant and inexpensive alternative to official LEMO-C connectors. Sure, they're not mil-spec but they do work and look great for DIY projects, keyboard builds, robotics, wearables, and more. The connector snaps together smoothly and can disconnect only when the sleeve is pulled, which can be done one-handed with a little practice.

These connectors are most famous for use by keebfans who make their own bespoke mechanical keyboard USB cables. Why? Why not!

This is the plug for a two-part set, you will also need the socket part that this plugs into, in order to make a full kit. Here's a video on how to assemble these sorts of cable connectors.

Once you have your cable assembly prepared, you'll then add the housings, strip the cable, tin the connectors and wires, solder the wires to the connector, heat-shrink the solder points, and reassemble the connector.
