Abstract

A pressure sensitive conductor consists essentially of (I) an electrically insulating rubber (excluding addition reaction type liquid silicone rubber), (II) 25 to 50% by volume of electrically conductive metal particles (preferably 40 to 200.mu. in particle size) and (III) 5 to 20% by volume of carbon black, and having a JIS A hardness of at least 40. Said conductor may optionally contain (IV) 0.1 to 5% by volume of a mono-, di- or trialkyl titanate. This pressure sensitive conductor has high mechanical strength, a rapid electrical response to deformations, a low hysteresis of the electrical resistance variation on application and release of pressure, and minimized change of the pressure-resistivity curve under repeated deformations.
