Does anyone know if the S5, circuit interrupter switch is an (mom.on / off / mom.on) DPDT switch? My 803 is completely missing the switch. I know the part number is an Eaton 8906K4519 but there is literary zero information out there about this switch and none of the Eaton/Cutler Hammer military/MilSpec catalogs show this part number. I'm trying to find a substitute to test run the generator until I can order the correct switch.
