You can make your own very accurate switches for very little money. These are what I use.

Yes I was thinking about using a hall effect sensor, seeing as I cut wood they would work for me, thanks for the info.

To be honest it's not worth doing unless you buy the sensor and Led resistors etc cheap has you can buy inductive prox switches for approx £2.80 from Ebay.

I bought these to try and they are fine giving repeatabilty much better than mechanical switches and simple and easy to adjust. They also allow higher voltage so can be used with 24V and kept in line with rest of system. They are more than good enough for a Wood router without the hassle of soldering and making holders etc.
