Kindly note that 1 qty = 36 sockets. Milmax sockets offer a balance between the original solder experience and the hot-swap experience that sacrifices sound quality. Introducing Mill-Max's latest creation: the 3305-X hotswap receptacles! These innovative, low-profile receptacles are designed to make your mechanical key switches easily swappable. They can be soldered into a small .060” (1,50mm) mounting hole and their ultra-thin shoulder allows plugged-in components to sit flush with the board surface. Its open-bottom design can also accommodate various lead lengths, making it a versatile choice. Kindly do your due diligence before purchasing. These sockets are basically to help convert a solder-only PCB into a pseudo hot-swap PCB. Base your purchase decisions on the provided specifications. All sales are final.
