ABSTRACT:
A food warmer includes a plurality of trays and associated lamps mounted on a frame for rotation in unison about a stationary standard. Each lamp is arranged above each respective tray to project heat downwardly only into the tray with which it is associated. The trays are pivotally supported on the frame and a switch associated with each tray is closed by pivotal movement of the tray upon placement of food on the tray to energize the lamp associated with the tray. A rotary connector is disposed between standard and frame, so that current can be supplied to each lamp regardless of the rotary position thereof. Each tray is detachable from the frame for cleaning and a switch override is selectively disposed between the tray and housing to prevent closing of the switch and energization of the lamp when necessary.
