Abstract
An electric motor driven coffee grinder is turned on by manually activating an on/off/start switch when a bag is in position to receive ground coffee under a discharge chute and automatically turned off when the bag is removed. The grinder motor is controlled by both the manual on/off/start switch and by a switch which is actuated by a pivotally mounted lever responsive to the presence and absence of a bag under the discharge chute. This lever is designed to assume a switch-off position when no bag is present and is pivoted to a switch-on position when a bag is present.
