DRY CIRCUIT TESTS AND TEST EQUIPMENT FOR ACCEPTANCE TESTING OF RELAYS FOR LOW LEVEL APPLICATION

Abstract

INVESTIGATIONS WERE MADE TO DEVELOP A SET OF AIRBORNE ELECTRONIC RELAY ACCEPTANCE TESTS WHICH WOULD ALLOW ACCURATE PREDICTION OF RELIABLE OPERATING RELAY LIFE. It was concluded that the general performance and reliability of a relay with respect to surety of contact appears to depend upon two main factors: (1) design and (2) manufacturing processes. Design can reduce or eliminate the problem due to particle contamination by insuring the high contact force and the relatively large amount of contact wipe required to maintain clean contact interfaces. Manufacturing processes can help produce a reliable product by reducing to a minimum the contamination included in each unit during its construction. It is important that those tests which attempt to determine contact reliability maintain operation in the low level area for each total contact operation to obtain the most accurate results; thus, the electrical test parameters must be as low as possible. Four different makes of relays, thought to be representative for hermetically sealed relays, were selected for this study and test. (Author)
