REED SWITCHING DEVICES.
Abstract
The results of a program for the development and evaluation of a reliable, long life miniature Form C switch capsule and a family of miniature electromagnetic relays compatible with miniaturized electronic equipment circuit requirement employing the capsule are presented. The program was conducted in two phases: The design, fabrication and evaluation of the reed switch capsule followed by relay design, fabrication and evaluation. Primary emphasis during the capsule design and evaluation phase was placed on the conduct of a full factorial experiment to ascertain the functional relationships of combined operational parameters on life expectancy of miniature Form C reed switches. A total of 135 Final Development Switches were tested under five combinations of temperature, load and drive levels. The test instrument designed and built to accomplish this phase is described, and the results tabulated for subsequent statistical analysis. Design details and the results of a test program involving 150 engineering samples, including the results of a relay life test experiment conducted under various combined operational levels of temperature, load and drive conditions, are presented for analysis to establish correlation factors between capsule and relay performance.
