ELECTRIC RESISTANCE HEATER AND LIMIT SWITCH ASSEMBLY Abstract A heater and limit switch assembly, particularly useful for installation in the conditioned air duct of a rooftop air condi- tioner. The loop of a rigid-loop heater, mounted on a vertical plate by two parallel legs, is modified to provide an inward off- set portion leading to the second leg. Radiation, from the off- set portion and its bend into the second leg, is received at close range by a simple disk-type limit switch, positioned on the plate outward of the second leg and facing the offset, inducing prompt response to any increase over design temperature.
