Just a quick little solution to a problem I faced in the shop…
I bought a switch for my router table so I could bump it “off” with my knee, and also not have to reach under the table all the time.
Only problem was that the switch was designed to be mounted with screws, and my table legs are pretty hefty steel.
I ended up cutting up a remnant of plywood and laminating a shape that would allow the final attachment to pull it together with enough force to bind it to the leg.
The front, where the switch is mounted, is just a rectangle of plywood. The back (working from back to front) is a similar rectangle with two independent “towers” that sit on each side of the 1/16” thick leg. I made the fit pretty snug, so even just this pressure holds it pretty well.
I placed it where I needed it (lots of knee-testing), clamped it pretty aggressively, and secured front to back with wood screws, pinching the fixture onto the leg. You can see the gap in the second picture where the compression occurs.
I can’t move it when I try, so it worked well. My backup plan was to compress a piece of sandpaper in there if needed, but the pressure from the dual axis pinching of the leg does it all by itself.
Edit: Added a drawing to better illustrate the plywood laminations and the forces on the leg
