Installed on my Delta Uni-saw and works fine. Tried to look up OEM switch from Delta, obsolete, no longer available?? When original switch started to give me trouble ( a few years ago) I did look up replacement - Delta then priced at close to $200.00. The original switch sometimes had to be manually reset allowing the saw to function. Finally got tired of that procedure. Grizzly order/delivery was quick and I will very likely be ordering from them in the future. I really prefer to keep all of my equipment OEM, but not when cost is 50% higher then OEM parts (if available). Thanks Grizzly!
