Instead of clipping on to the top of the PCB like non-waterproof connectors, these punch through the bottom of the strip to make a secure connection to the PCB without the need to remove any of the silicone coating. Now you can connect wire to waterproof strips quickly and effortlessly without compromising the waterproof nature of the strips. 10mm 4-conductor strips are normally used with RGB color changing strip lights.
