  • Means for preventing an electrical shock hazard
    Patent number: 3965397
    Abstract: An interlocking safety arrangement for electrically powered apparatus utilizes a conventional disengagable electrical connector and a standard fuse holder which are physically arranged so that the connector must be disengaged from its receptacle to gain access to the fuse holder. Since the electrical connector supplies power to the apparatus, disengagement disconnects the power and prevents the possibility of an electrical shock hazard from the terminals associated with the fuse.
