Abstract
A PTC thermistor switch for electric motors includes an insulating casing and a PTC thermistor housed in a housing seat made in the insulating casing. The PTC thermistor has a first face and a second face opposite the first face. A first electric terminal is housed in the insulating casing and has two protrusions in direct contact with the first face of the PTC thermistor in two opposite contact points with respect to the center of the first face. The switch also includes a second electric terminal housed in the insulating casing and an elastic arm portion in direct contact with the second face of the PTC thermistor in an intermediate contact point between the contact points of the protrusions. The second electric terminal is arranged so that the elastic arm portion presses against the second face of the PTC thermistor.
