What Limit Switches?

[A_Camera]

So looking for both homing and limit switches.

This is for Thor which will have movement speed of at least 10m/min. Mechanical or Proxy? Will possibly using Index homing once sorted but I need to be able to stop a servo run away, so looking for something that will work and reliably.

I definitely vote for mechanical NC limit switches. The reason is that if something goes wrong with them the machine stops, you look for the error and eventually will find it. If you use proximity switches this may not always be the case, regardless if you use NC or NO type. Of course, for limit switches, nothing else but normally closed (NC) should be used, they guarantee broken wire detection also, which you can't have if you use normally open connection.

For home switches... well, I think mechanical is best but accurate mechanical switches are very expensive. I don't use any home switches, but have heard that proximity switches are accurate too. I guess it depends on the accuracy you need and the method of homing. Some software are better than others.
