Comparison between different Mill Max 0305 vs 7305 vs holtite and the new mill max 3305 sockets for custom keyboards.
Mill Max sockets 0305 – budget, good if you have enough room between the PCB and the case, easier than 7305 to solder
Mill Max sockets 7305 – more expensive than 0305, good if you don’t have a lot of room between your PCB and the case, more difficult than 0305 to solder.
Holtite – more expensive than 7305, good if you don’t have a lot of room between your PCB and the case, can be used unsoldered if not planning to hotswap frequently the switches, but more difficult to solder than 7305 if decided to be soldered.
Thanks for this info to u/nineleveno:
Looks like Mill-Max also makes 3305 sockets now, which are made specifically for keyboards with a thinner lip than 7305 (0.25mm vs 7305’s 0.36mm) and same length as 7305. It is more expensive than 7305 though.
