MIL-PRF-8805/100G
Movement differential: .035 inch maximum.
Overtravel: .250 inch minimum.
Coincidence of operating and releasing points: All circuits shall transfer within .010 inch of plunger
travel after first circuit transfers.
Strength of actuating means: 100 pounds minimum.
Azimuth adjust nut: No damage to switch or azimuth adjust nut shall result from torquing this nut to 15
pound-inches minimum.
Finish: All external surfaces of switch housing, including threaded bushing and bracket, shall be both
corrosion resistant and electrically conductive. Cadmium plating shall not be used.
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.
Mechanical endurance: 25,000 cycles.
Electrical endurance: 25,000 cycles.
Low level circuit: 1,000 cycles at 85°C. (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
meghohms.
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 100 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.
