ABSTRACT:
An electrically powered can opener includes a can cutting element carried on a mounting plate which is pivoted to the can opener frame. An operating lever is connected to the mounting plate for limited pivotal movement beyond which the plate and lever pivot unitarily on the frame. A notched area on the hand lever becomes engaged against a catch member on the frame to retain the lever in place when it is brought into position to shear a can lid. The lever is held against a plunger switch which maintains the motor in its energized condition during shearing of the can lid. After the completion of the shearing when the operating thrust is no longer present, biasing forces acting on the lever disengage it from the catch member and release the plunger for automatic shut off of the motor.
