Spring-loaded sliding mount for a good old mechanical micro switch. Has about 6mm of travel (1/4") so get it close then fine tune the deck height.
This works really well and is a nice example of close tolerance sliding parts printed in PLA.
Found these cheap and nasty micro switches on fleabay for a few cents each. http://www.ebay.com/itm/261071015810
