Old style electromagnetic dual coils relay cannot be found by many technicians. These were new extras, used for the electrical pole boxes of Georgia street traffic light signals many years back. Most nowdays are solid state replacement. These specialized relays were used in alternate energy tests due to exquisite properties. AC , 60 cycles, switching, latching, dual inductors, each about 1.5 Millihenry #21 gauge magnet wire, .7 ohms per coil, diode inbetween coils, coils each 1 3/4" by 3/4" with small core. The bakelite outer black housing has no bracket, no markings, screw terminals on outside, and looks like an old vintage relay. The units are enclosed in VACUUM , so as will be extremely reliable in all weather conditions 24 hours a day, all year. The alternate energy web site was closed down since no more than the original 15 can be found. Search Please!
