MIL-PRF-8805/100G
REQUIREMENTS:
Dimensions and configurations: See figure 1, 2, 3, and 4.
Enclosure design: 4 (Resilient) All entrances to the switch cavity, except through the actuator bushing,
shall be sealed by fusion of glass to metal, or ceramic to metal, and the lead wires shall be potted to
provide stress relief.
Temperature characteristics:
1 (-55°C to +85°C) continuous duty plus switches shall be subjected to 100 cycles of temperature
variations. One cycle is defined as the temperature and times, in order shown, in table I.
Immediately upon completion of testing of a temperature requirement, the switches shall be inserted
into the subsequent test chamber. At the end of the temperature condition of each cycle, the
switches shall make, carry, and break rated resistive current at rated voltage (sea level) for the
number of operations shown in table I. Test shall begin after oven temperature stabilizes. Prior to
each make/carry/break operation involving rated resistive current the switch shall carry without
making or breaking 400 percent of rated resistive current for 200 milliseconds. Failures, defined as
the inability to make or break rated resistive current, shall not occur throughout those tests.
