I've completed the design for my pool timer and now I'm down to designing how this board will actually hold itself inside an enclosure. I already have a box that I'd like to re-use. It looks like the t30004r.
I plan to take out the 2 mechanical timers and insert my 3"x3" PCB in there, but I need to mount it inside the box in a safe way. The PCB itself has external connections coming out on all sides and I'm using many hole-through components. In addition, I also plan to use the 2 switches that are a part of the panel to still allow the control of the light & pump. The board takes in 120VAC so I want it to be secure.
The main option here seems to be adhesive standoffs. Are there better solutions? Any concerns that I should have with adhesive standoffs? I do still want it to be removable.
