I use a bunch of GX16 (at least, that's what the Aliexpress seller called them!) for signal connections on my control box and never actually put one alongside the spindle connector to look at the difference. Just assumed that they were the same as they are superficially very similar. So much for assumptions! Surprised if they had a much higher current rating as the pin/socket size must be very similar but I guess that it's all down to how well they fit, spring mechanism, etc. Thanks for the correction, Rob - if I ever need to replace my spindle connector I'll make sure I get the right thing!
