# PCB-mount vs. Plate-Mount Switches FAQ + For technical questions, check out the [Keebio documentation site](https://docs.keeb.io/) + Which type of switches do I have to use, PCB mount or Plate mount ones? + The only difference between the two is that PCB mount has two additional plastic legs for better alignment on a PCB. Either type is compatible with Keebio PCBs, and if given the choice, PCB mount is preferable to keep switches aligned better. + Can I use hotswap sockets? + Holtites: Not recommended, they suck, use them if you want to have a bad time + Mill-Max: We use these for [our](https://keeb.io/products/mill-max-hotswap-sockets?_pos=1&_sid=9beee6bc3&_ss=r) hotswap [boards](https://keeb.io/products/iris-keyboard-pre-built?_pos=2&_sid=9beee6bc3&_ss=r), and they work well. + Outemu sockets: Yes, but they only fit Outemu switches or Pandas + Kailh hotswap sockets: No, PCBs have to specifically be designed for them. See the image below that shows the parts that can't fit onto the PCB. ![](https://i.imgur.com/jowodfJ.png)
