About homing and switches...

[john swift]

it depends on the budget your working to

if its a hobby machine then try amazon or ebay etc
buy 1 to check the quality then order the others you need

for a business machine you use to make a living
look at industrial suppliers like RS Components , Farnell or Rapidonline
for original proximity sensors not the cheep clones found else ware online

you will pay more but they will be to the published specification

Don't waste money buying the expensive switches Just buy the cheap Chinese switches off ebay.

I've fitted 100's and probably had about 3 in total that was faulty out of the bag. I've had about 5 fail in use over a 10yr+ period all on different machines.
The accuracy is more than good enough for any Router or DIY Milling machine.

The IP/M doesn't care which you use but I always fit NPN switches.
