RESEARCH AND DEVELOPMENT TO DESIGN, FABRICATE AND EVALUATE SINGLE POLE DOUBLE-THROW DRY-REED CAPSULES AND RELAYS USING THESE CAPSULES.

Abstract : The purpose is to obtain performance information on SPDT Dry-Reed (GenReed C) Capsules and to provide designs and performance information on relays using these capsules. Operating characteristics on an initial run of capsules reported. Additional data shown on Load Determining Life Tests at four load levels; 1/4, 3/8, 1/2 and 3/4 amp., at cycling rates of 32 cpm and 30 cps. Testing at 30 cps has been completed. Most of the switch capsules were still functioning reliably when testing was discontinued after more than 9.5-million operations. Testing at the 32 cpm rate is approaching 4-million operations and tests are continuing. (Author)
