I am trying to build a big push button in the shape of a rectangle. I have 4 springs at each corner (below the plate), but the problem is, that because of button's size, if I press down on one of the corners, only the spring closest to that corner will compress.
I am looking for a mechanism that would allow me to somehow "connect" those 4 springs, so when I compress one of them, all others will also compress. I've looked online, but I feel like I'm missing some core terminology here and I am unable to find anything useful.
I think that I could probably solve this by simply getting a very big spring and placing it at the center, but at this point the springs are getting very expensive, and I hope that there is a more clever way of doing this.
Any help would be greatly appreciated.
