could you post a scheme to assembly to mightyboard? resistors needs to be used?

Why don't you add the design files (openscad etc)?, switches are quite different and one cannot customize it.

Ingenious,very well done:-)

This will also work on a printer running Marlin firmware. All you need to do is set the switch to activate the M600 "Filament Change" code. I used this forum topic to get it working : http://forums.reprap.org/read.php?1,297350,381605

Can you tell me the part number for the Omron ball roller switch that you used?

Sure will, however at the moment I'm out of country on a business trip in PI. I will answer as soon as I return/ get a chance.

very nice idea! I would suggest opening the connector holes a bit wider though, so that you can use a blade connector and not just push wire through the hole / solder it into place. It looks like your switch is designed to do both, but Blade connectors are easier and removable (as compared to solder)
