Hi, I made a series of switch motor boxes, each with a different style of hole for weather testing:
1: box without any additional holes.
2: box with the "throw lever" switch installed.
3: box with 0/039" hole and 0.039" rod.
4: box with 0.039" rod running thru 1mm ID silicone sleeve.
5: box with 0.039" rod running thru pair of 1mm ID silicone o-rings.
I placed a cobalt chloride moisture and humidity detection test paper inside each box.
The boxes have clear lids so I will be able to monitor them for leaks without opening.
The boxes are positioned on the trestle with the holes facing the wind/snow: 02-17-2020: 4" snow storm last night, all boxes dry inside
I took a chance and placed a "medium run" order for 40 of the PCBs.
