Limit switches PCB schematic verification.

[cncnoob]

Hi guys.

Would it be possible for some one to have a look at this schematic for limit/home input PCB that I was looking to build?
[Please see attached..]


I'm sure I've either missed some stuff or maybe just done something plain and simply wrong.

Just wanted confirmation that this should work before I plug it all in..

I have a my control unit plugged in to the original port on my PC, so thought I would buy a PCI card and wire this to the second.

The 5v supply will be provided by a wall adapter.

All switches will be NC. Thinking of making a probe, and a few other input devices, probably wont use all connections to start, but want the option to do more later on one board.

Thanks in advance for any feedback, I will appreciate it!
