Home DIY - Kitchen Bin Magnetic pushbutton

As usual, when you buy cheap things, you can not expect them to last forever...

I bought a common trash bin to be placed in the kitchen, but in few weeks the release button has been destroyed...
For not to go buy another one, I try to get a solution by drawing a replacement button with some improvements.

The new release button use two recycled magnets as "spring" for rearm!
The magnets are recovered by some cupboard magnets I found at home.
The extra material needed is a steel bar of 5m
