A blade heating system for a heated razor includes electrically conductive blades contained in a blade cartridge. A switch lever is hingedly attached to the blade cartridge and is selectively positionable between a closed position, wherein the switch lever is closed against the back of the blade cartridge, and an open position, wherein the switch lever is opened away from the back of the blade cartridge. Electrically conductive leads are connected to positive and negative terminal ends of a battery carried on the switch lever. One or more electrically conductive blade contacts are provided for electrically connecting the one or more blades to the conductive leads and battery when the switch lever is in the closed position for delivering electric current to the one or more electrically conductive blades. In a preferred embodiment, magnets are used to releasably hold the switch lever closed against the back of the blade cartridge.
