Abstract
An improved electrode construction for use in telephone protector modules, characterized in at least one of the pair of electrodes having an operative surface thereon defining a plurality of radially extending, generally pie-shaped sections forming plateau areas separated by radially extending grooves which serve to collect eroded particles and provide a means for venting the particles from the air gap separating the pair of electrodes. A centrally disposed circular recess joins the grooves and enables the venting action to be distributed to each of the grooves upon firing.
