On all types I’ve flown the load release button is very similar to switches used for trim release/SAS disengage or floats actuation but they are guarded by a flip type cover.
Some switches are actuated by pressing the guard which is flipped over through 180 degrees.
One type I flew (S-76) had the float actuation switch in the place on the cyclic where the load release was on the previous type I’d flown most (Puma). I had to think carefully when carrying out USL work.
