I bought a used drill press and its switch was broken. I ordered this one as a pin-for-pin replacement AND it had the benefit of the safety feature that you could stop it by slapping it, AND it has a lock-out key. The price, like everything Grizzly sells, was just down-right inexpensive. I recommend you change buy this and change out all your equipment switches if they aren't safety types that takes this form factor. For larger gear like table saws, Grizzly sells full size AC switches.
