Not sure if it is true, but I was told that fish oil was used in the material composition for the “self lubricating nature” of these switches. Probably got trolled, but if this is true, that would explain the smell. Both my Creams and Blueberries reak of this. Opened my bag of Blueberries and told my wife they smell like fruit and to take a big “sniff” lol. She was not pleased.
