This was exactly the replacement I needed for my Kenmore smooth top range.  There are 4 holes so that you can get the proper alignment with the knob.  All stoves are essentially the same and use some version of this type of switch.  Everything was labeled and hooking up was as easy as looking at the picture on my phone that I took and putting them on the right prongs on the new one.  Worked perfectly.
