Hi everyone, I have two aluminium detail with flat surfaces, that I want to connect one to another. (let's say around 2-3 cm2). One of them is on the top and it fixed to my setup. Another one is on the bottom. There will be a distance between them around 3-5 mm for PCB, that will be connected to the bottom part. I want to have an opportunity to easily disconnect the bottom part with pcb. I mean no screws and nuts. I am thinking about some spring - like in a pen - click - and it fixed, another click and it unfixed. Or some nut with no thread, but with a button to fix/unfix it. Please, advice me some keywords, with which I will be able to find some suitable solution in a shops. Or advice me your solution, Thanks in advance!
