The contact plates for the Harrel-RacingStandard Powerslots are punched out of a 1mm thick stainless steel plate. Continuous control ensures quality over high quantities. Magnets adhere to the material, which is an important advantage for drivers who use magnets. In a Harrel-RS road module, the poor conductivity of the stainless steel is compensated by a copper strand. It connects the plugs at the ends of the module and transfers the energy to the steel plate.
