Leach Relays

Leach relays were relied upon by Lt. Col. John Glenn, first U.S. astronaut chosen for orbital space flight around the earth. Photo shows some of 116 relays, specially tested but "off-the-shelf" stock, used in connection with various power switching devices on the Mercury space craft. Leach relays have been know to work continuously without failure 8 hours a day, 5 days a week for over 30 years., Credit Line: AIP Emilio Segrè Visual Archives, Physics Today Collection
