ABSTRACT:
A stove timer and automatic cut off system is provided including a stove having a plurality of burners each adapted to generate heat upon the receipt of power. A start switch situated on the stove is adapted for transmitting a start signal upon the depression thereof. A timer selector switch assembly is situated on the stove and has a plurality of discrete modes. The switch assembly is adapted to transmit a timer signal representative of a unique predetermined amount of time in each mode. An indication means is situated on the stove and is adapted to alert a user only during the actuation thereof. A relay is connected between the burners of the stove and a source of power. The relay is adapted to supply the burner with power only when actuated. Finally, a control mechanism serves to function in an activated mode only upon the receipt of the start signal wherein the control means actuates the relay. The control mechanism, while in the activated mode and upon the cessation of the predetermined amount of time represented by the timer signal, is adapted to actuate the alarm for an interim and further deactuate the relay and the alarm upon the cessation of the interim.
