MIL-PRF-8805/104D
Contact resistance: Low level circuit requirements apply.
Dielectric withstanding voltage:
Sea level: 1,250 V rms.
Altitude: 600 V rms at 80,000 feet.
After electrical endurance, the dielectric withstanding voltage points of application
between all unconnected terminals of the same pole is not applicable.
Seal test: Only watertight test shall be performed in group A.
Mechanical endurance: 25,000 cycles.
Electrical endurance: 25,000 cycles.
Low level circuit: 25,000 cycles over the continuous duty temperature range (applies
provided switch has not made nor broken more than 250 milliamperes at 6 volts dc or peak
ac).
Electrical ratings: See table II.
Moisture resistance: When switches are tested wet, the insulation resistance shall not be
less than 100 meg-ohms.
Icing: Applicable.
Case and plunger grounding for EMI: All case parts shall be bonded together (such as by
staking, soldering, welding, or brazing) either along the entire abutting surfaces or at a
minimum of four approximately equally spaced areas along each abutting surface. The
electrical resistance between the plunger and the wire exit portion of the switch housing
bracket most remote from the threaded bushing shall not exceed 800 milliohms under all the
following conditions:
a. Measurements made in accordance with MIL-STD-202, method 311.
b. Without polishing or cleaning the areas on the switch to which the test leads are
attached.
c. With the plunger both fully extended and fully depressed.
d. Throughout the total life of the switch.
