Needing a power switch for my Black & Decker 8" induction motor table saw. Cat 9419 type 2 part number 121885-01. I was told that this model was discontinued in 1992 but its still running like a beast and only needs a switch. I was thinking of replacing it with a more conventional switch (double pole, double throw, dpdt) but i want the safety feature to stay. Cant find the part anywhere, its built by lucerne U.S.A switchs. Are there any out there or a comparable model that would fit?
