  • Patent number: 6183264
    Abstract: A safety outlet receptacle with a corresponding plug that renders the outlet receptacle inactive and unable to transmit an electrical current unless activated using the corresponding plug. The invention uses a very simple magnetic switch that is biased with a spring to change the activity state of the outlet receptacle. A single matched magnet and ferro-magnetic base is used to activate the magnetic switch. The invention can be used to replace any type of standard outlet receptacle regardless of the electrical power that is being utilized such as 110 or 220 volt, 50 or 60 cycle, AC or DC. The invention also features an indicator light in order for a user to be certain that the outlet receptacle needs to be replaced because it is no longer operating in a safe manner.
