Abstract
A hair cutting appliance is presented including a body with a power switch and a power source. A drive system within the body is in selective electrical communication with the power source. A cutting unit is coupled to the drive system. An optical sensor is positioned to sense a pre-defined skin-hair edge in an area in front of the cutting unit. A switching element is in electrical communication with a control circuit and switchable between a conducting state to electrically connect the drive system and the power source and a non-conducting state to electrically isolate the drive system from the power source. The switching element is switched to the non-conducting state when a first sensed condition of the optical sensor exceeds a first pre-programed threshold. A power transform module is also provided that includes the optical sensor and is configured to be mounted to the body.
