Abstract
The invention relates to a pressure-sensitive conductive elastomer compound which exhibits high resistance (insulating performance) when it is in non-pressed condition and the resistance of which, as the compound is pressed, varies according to the magnitude of the pressure. The compound comprises a matrix material having insulating and elastomeric properties and baked and carbonized conductive spherical particles of a macromolecular material incorporated and dispersed into the matrix material. The conductivity of the conductive particles varies according to the degree of their carbonization.
