ABSTRACT:
An electric oven toaster construction wherein a unique rotatable cam controls the bake, toasting and broiling modes of the oven toaster and simultaneously sets the threshold temperature of a thermostat switch during toasting, baking and broiling. The rotary cam includes a rearwardly extending rod portion having a radially outwardly extending lobe for cooperating with a cam follower portion of a bake switch for opening the bake switch when a bake operation is set and closing the bake switch when a toast operation is set. The rotatable cam also includes a circular disc portion positioned in front of the rod portion and integrally formed therewith. The circular disc portion has a cam surface that extends rearwardly and is in sliding engagement with a thermostat cam follower blade to set the thermostat cam follower for a particular toast color. Thus, with the unique integrally formed cam, when the cam is simply rotated to the toast position, the cam simultaneously closes the bake switch so that a solenoid will be energized to open the main switch when the toast cycle is complete and the cam also sets the thermostat cam follower to select a particular toast color.
