Reed switch for limits - anyone done it?

I was considering using small magnets and micro reed switches
mounted into the base of my Sherline mill to be used for limit and
home switches. I figured that mounting magnets into the underside
of the table and the switch in the mated surface would be a good
solution; nothing exposed, nothing to break is overtravel happens
and fast switches.

Before I drill and mount I thought it a good idea to check the group
and see if anyone else has gone this route and what they thought of
the idea (good or bad).

Thanks,
Ken
