The 40mm mushroom head is genuinely massive, so even a panicked slap from the side hits it easily, and the click when it locks is reassuringly firm. I’ve tested the reset a dozen times and it never sticks, which is exactly what you want when your heart’s racing.

Had a small mishap with my table saw last week and this button stopped it instantly. The ABS body feels solid and the resettable twist is smooth—exactly what I needed for my shop setup.

The 40mm mushroom head is huge, so my palm hits it instantly without fumbling. It clicks into place with a satisfying, solid lock that I can feel even through gloves.
