ABSTRACT:
A toaster/oven having a door and a door frame and door jam peripherally surrounding the cooking chamber front opening. The door is pivotally mounted on two hinge pins, a first hinge pin being received in an opening on one side of the door frame and a second hinge pin being received in a slot on the other side of the door frame. The geometry of the slot and pin position on the door is such that the door is not removable except when in its fully opened position. The toaster/oven also comprises door retention means for selectively holding the door in a closed, partially open broil and a fully opened position. The pivotal movement of a lever arm operates first and second switch means which respectively cut off power to the heating elements of the toaster/oven and provide a signal to the controls of the toaster/oven when the door is open. The switches comprise leaf spring conductors biased toward terminals, and a bell crank rocked by the lever arm displaces the leaf spring conductors from their respective terminals to open the switches.
