Dual voltage systems 14/42V are about to be adopted on cars. Electromechanical relays will probably be replaced by semiconductor smart power switches, particularly in the command of fans, compressors, motors and heaters. On the other end, the use of electro-mechanical devices which guarantee low contact resistances (< 0.3 mOhm) substantially temperature independent, high continuous currents (150 - 200 A) and high peak circuit currents (600 - 800 A) during transients and in case of overcurrent, represent an economic alternative to complex high power semiconductor switch. The paper will explore issues related with the design and the implementation of high current contact configurations for future 42V systems in order to fulfill low contact resistance and to increase high current interruption capabilities. Further studies will be carried out increasing the operating voltage up to 58 - 60 V also if the occurrence of overvoltage pulse of 58 V, 400 ms will be exceptional.
