Hy there, 

I wasn't sure if I should upload this design, it's a little tricky to print, that's why I added a picture of my orientation in the slicer and also fiddly to connect wires and mount the Switch inside the housing. 
But I got it to work on the first try and am very pleased with the end result, so I uploaded it anyway. 
I also add the step file in case anyone wants to optimize it.

Hope you will be as satisfied as I am.

Have a great day
