ABSTRACT:
For use with coffee bean grinders, a safety switch is actuated by a pivot arm having a pivot point located below a contact area at which a removeable container engages the pivot arm. The pivot arm pivots about the pivot point on a substantially horizontal axis between a forward and a retracted position. Also, the contact area is disposed forwardly of a vertical plane containing the pivot point and the horizontal axis. This construction reduces the amount of force necessary to move the pivot arm and actuate the switch. Because this force is smaller than before, this safety switch can be used with thin-walled containers, like plastic bags, without compromising the proper operation or safety of the grinder.
