Patent ID: 7762049

Claim:
An electric outdoor power machine comprising: a machine body supported by wheels and having an output member driven by a motor, the motor being powered by a source of electrical power; an upright assembly extending from the machine body and having a gripping handle; a manual input member adjacent to the gripping handle and movable relative to the gripping handle between a deactivated position and an activated position; and a control assembly that selectively communicates electric power to the output member, the control assembly comprising: a button supported by a housing on the upright assembly, the button movable between an unactuated position and an actuated position; a button crank coupled to the button and having an interface portion; a rocker switch that rotates about a rocker axis, the rocker switch having a switch input member movable between an “ON” position and an “OFF” position, wherein in the “ON” position, the rocker switch electrically connects the source of electrical power with the motor, the rocker switch further comprising a biasing member that biases the rocker switch toward the “OFF” position; and a pawl extending from the manual input member; wherein the rocker switch is rotated around the rocker axis to the “ON” position by sequential movement of the button into the actuated position followed by movement of the manual input member from the deactivated position to the activated position, wherein movement of the button into the actuated position operatively moves the interface portion of the button crank from an offset position relative to the pawl to an aligned position with the pawl such that movement of the manual input member to the activated position causes the pawl to move the interface portion into contact with the switch input member which in turn rotates the rocker switch to the “ON” position.
