Abstract
This ATM details the investigation to determine the reliability characteristics of the Teledyne 421, latching relay used to generate the "3-month" output signal of the ALSEP Solid State Timer. The investigation was performed to establish the susceptibility of the relay to "cold welding" over the two-year operational life of the ALSEP system.
