Abstract (en)

[origin: ES8601624A1] The resistance heater is arranged on a ring-formed insulated body which itself is attached to the housing of the air heater. The winding loops of the heater are formed to stand free of the insulated body, and are secured by the clamps. A bimetal switch, in series with the heating resistances, acts as a heat loss protection switch, and it is located on the column which is fixed to the insulating body and holds the terminals. The bimetal switch can be fastened to a recess on the column and then connected to the circuit. - The column has two projecting pieces with the terminals: one some distance from the insulated body and one close to it. The end leads of the winding are connected to these two terminals, one on one side of the column and the other on its other side. The purpose of this arrangement is to ensure accurate activation of the bimetal switch.
