Re: Homing switches

Hello,

Dan Hudgins (Dancad/cam) published some "notes" about using this
arrangement for an accurate home position. You can use a slot in a
disk mounted on the l/s with the optical detector Chris mentions, in
concert(AND-ed) with a microswitch. This means the microswitch does
not need great accuracy, since the l/s rotation will be the "final"
determinant of home posotion.

Getting to your original question, true HOME switches are EXPENSIVE!
And the best way to figure which to use is to work with an
applications engineer at one of the bigger switch companies...

These guys will ask what you are trying to accomplish, then put their
years of experience to work for you! Not bad for the price of a phone
call! (emails don't work as well, IMO) Don't be afraid to ask
questions; this is their job.

Hope this helps.
