On/Off Knob used on the Encore, Maestro, Maestro Classic, and Starbucks Grinder without Solis branding. The switch on all of these models switches the grinder to an on position, which must then be manually turned back to an off position. This is different from a wind-up timer switch that automatically switches the grinder off, used on models such as the Maestro Plus. This knob does not fit models with a timer switch.
Baratza has made rolling changes to the knob/switches used throughout the conical grinder range, and it can be easy to mix them up. Please verify the part number is compatible with your machine’s model prior to ordering. Parts may look the same but the size and shape can have variations.
