ABSTRACT:
An arrangement of electrode for positive temperature coefficient semiconductor (PTCS) for use in heating and drying devices and the like, which PTCS is provided with a pair of electrode plates, each having a fork-like configuration with a plurality of branches or fingers in the form of strips extending forward from its base. The strips of both electrodes are disposed alternately on one of the opposing planes of the PTCS body. Each electrode has an extended portion serving as terminal which is bonded on the other plane of the PTCS body in such a manner that the terminal is not confronted, through the PTCS body, with any strips of opposite electrode.
