The burner switches should not be changed. I am all for finding suitable substitutes, but in the past when I have used the universals, they don't always act right. They are sized to the burners for a reason, and when your dealing with 220 volts going into the switch, I always use the switch that is called for that particular burner. Not to mention the cheesy universal shaft adaptors. They do not always line up the knobs correctly. I will only use them when I call up and normal switch is discontinued or NLA> Like on some real, old cooktops.
