An electrical safety thermal switch, essentially characterized by the fact that it consists of a box that carries the coupling terminals and a button for internal connection, this connection being provided to be canceled at the moment when there is an abnormal increase in the intensity of the current, to which end there is a retention that maintains in coupling a mobile contact with respect to a fixed one, the movable contact being retained by a blocking finger belonging to a bimetal sheet that deforms to the abnormal passage of the current through of a strong thread that surrounds it, the movable contact comprising a bridge attached to a rod that is surrounded by a helical spring and ends externally in the said button.
