  • Current limiting element for preventing electrical overcurrent
    Patent number: 4101862
    Abstract: A current limiting element for preventing electrical overcurrent manufactured by mixing conductive particles with an elastic insulating material which possesses a positive coefficient of thermal expansion, such that particles are normally in electrical contact with each other, and the elastic material interposed between the particles is caused by heating to expand so that the electric circuit is interrupted.
