Appliance timing system

An appliance timing system for permitting a user to use an appliance for a pre-determined amount of time, the appliance timing system comprising:

• a housing has a perimeter wall defining an interior space, said perimeter wall of said housing being adapted for coupling to the appliance;
• a switching assembly being positioned within said interior space of said housing, said switching assembly being operationally coupled between the appliance and a power source, said switching assembly being adapted for allowing power from the power source to be provided to the appliance when said switching assembly is actuated by the user;
• a card being insertable into said interior space of said housing through a slot in said perimeter wall of said housing, said card actuating said switching assembly when said card is inserted into said slot of said housing by the user such that said switching assembly permits the power supply to provide power to the appliance;
• and
• a timer assembly being operationally coupled between said switching assembly and the appliance, said timer assembly being adapted for allowing the appliance to operate for the predetermined amount of time before discontinuing power to the appliance;
• wherein said switching assembly has a pair of contacts, said contacts being positioned within said interior space of said housing, said contacts being in a spaced relationship with each other, said contacts selectively contacting a conductive strip on said card when said card is inserted into said housing, said conductive strip of said card permitting electrical communication between said contacts when said card is inserted in said housing such that said conductive strip operationally couples said timer assembly to the power supply;
• wherein said switching assembly has a first switch, said first switch being operationally coupled between the power source and an first of said contacts, said first switch being actuatable when said card is inserted in said housing, said first switch being adapted for controlling power from the power supply to said first of said contacts such that said first switch permits power to be supplied to said first of said contacts when said first switch is actuated by insertion of said card into said housing;
• wherein said switching assembly has a second switch, said second switch being operationally coupled between the appliance and a second of said contacts, said second switch being actuatable when said card is inserted in said housing, said second switch being adapted for controlling power from said second of said contacts to the appliance when said second switch is actuated by insertion of said card into said housing and said conducting strip of said card electrically couples said contacts;
• wherein said switching assembly has an activation bar, said activation bar being slidably coupled to said housing within said interior space of said housing such that said card engages said activation bar when said card is inserted into said interior space of said housing, said activation bar being coupled to said first switch and said second switch such that said activation bar actuates said first switch when said card engages said activation bar;
• wherein a first relay being operationally coupled between one of said contacts and a second relay, said second relay being operationally coupled between said first relay and said timer assembly, said first relay being adapted for being energized by the power supply, said second relay being energized by said power supply through said first relay when said contacts contact said conductive strip, said second relay being for activating said timer assembly when said second relay is energized such that said timer assembly permits operation of said appliance for the pre-determined amount of time;
• wherein said conductive strip of said card comprising a fusible link, said fusible link opening when a electrical current through said conductive strip exceeds a predetermined value such that electrical communication between said contacts is broken;
• wherein said card has top wall and a bottom wall, said top wall and said bottom wall comprising a non-conductive material, said conductive strip being positioned between said top wall and said bottom, said bottom wall has a pair of apertures through said bottom wall, each of said apertures being aligned with one of a pair of ends of said conductive strip of said card, said apertures allowing each of said contacts to contact said conductive strip when said card is inserted into said interior space of said housing;
• wherein said housing has a has a pair of rails, said rails being positioned within said interior space of said housing, said rails being extending from said slot in said perimeter wall such that said rails are for guiding said card into said interior space of said housing when said card is inserted into said housing;
• wherein a first light being coupled to said housing, said first light being operationally coupled between said switching assembly and the power source, said first light emitting light when said power supply supplies power to said switching assembly and said first light;
• wherein a second light being coupled to said housing, said second light being operationally coupled between said switching assembly and the appliance, said second light emitting light when said card is inserted into said interior space of said housing and actuates said switching assembly, said second light being adapted for indicating to the user that said timer assembly is operating.
