  • Devices of this type are commonly called shutter devices and hereinafter called shutter devices. They tend to become widespread in household applications in order to protect users and more particularly children.
  • discriminated devices are commonly called polarizing or discriminating devices, hereinafter called discriminated devices, because they make a difference between unauthorized male plugs and male plugs authorized to be inserted into the female plug. These discriminated devices are often used to dedicate a power line to computer devices and prohibit the connection of other devices on this line.
