Know before you buy
These sockets are designed to convert a standard soldered mechanical keyboard PCB into a hot-swappable one. By soldering these into your board, you can swap out mechanical switches without needing to desolder them each time.
The 3305 series features a shorter lip compared to other models. This design allows the switch to sit closer to the PCB, ensuring better compatibility with various keyboard cases and plates.
You will need two sockets for every individual switch on your keyboard. For a standard full-size keyboard, this typically means you will need 208 sockets, though you should verify your specific layout's switch count before ordering.
The 3305 sockets are compatible with most standard MX-style mechanical switches. However, they are designed specifically for through-hole soldering onto PCBs, so ensure your PCB layout supports the necessary footprint.
The Tin over Nickel plating provides excellent corrosion resistance and durability. This finish ensures a reliable electrical connection and helps maintain the integrity of the socket over many switch insertion and removal cycles.
