Mazzer Hopper Safety Switch

Used in the ‘E’ version Kony, Major, Robur and Royal, and the doser versions of the Kony, Major, Major ‘Grocery’, Robur, Royal and Stark model Mazzer grinders – basically any newer version that has the black locking tab style hopper throat adapter. This is the switch responsible for allowing the grinder to turn on only when the hopper is installed.
