Abstract : The purpose of this investigation was to provide models and performance information on relays and ferreed devices employing glass sealed contacts. Single-make, dry reed sealed contacts were used in the ferreed devices, while single-make and three-element-transfer dry reed sealed contacts and mercury-wetted, position-independent, transfer sealed contacts were used in the relay models. Exploratory environmental tests were conducted on representative samples. The results of these studies as well as the operating characteristics of all samples furnished to the USAELRDL are presented.
