MIL-DTL-13484G
3.5.3 Overload capacity. The switch shall withstand 100 make and break cycles while carrying a
rated resistive load current of 22.5 amperes. Subsequently, the switch shall meet the requirements of
3.5.4 Insulation resistance. The insulation resistance between open contacts of the switch shall be
not less than 500 megohms (see 4.6.4.4).
3.5.5 Open circuit resistance. The resistance between open contacts of the switch shall be not less
than 1 megohm (see 4.6.4.5).
3.5.6 Endurance. The switch shall withstand 25,000 make and break cycles while connected to
either a rated inductive, load current or rated lamp load current of 7.5 amperes. Subsequent to cycling,
the contact voltage drop shall not exceed 300 millivolts (see 4.6.4.5).
3.6 Environmental requirements.
3.6.1 Corrosion. Subsequent to testing as specified in 4.6.5.1, the switching mechanism shall
evidence no corrosion.
3.6.2 Fungus. The switch shall evidence no deterioration after testing as specified in ASTM-G21 for
a period of 90 days. The switch shall subsequently meet specified requirements (see 4.6.5.2).
3.6.3 Waterproofness. The switch shall evidence no leakage when tested as specified in MIL-HDBK-
1184, method 100, and shall subsequently meet specified requirements (see 4.6.5.3).
3.6.4 Extreme temperature. The switch shall operate for 1000 cycles (see 4.3.1) throughout a
temperature range of -54ºC (-65ºF) to 74ºC (165ºF) with a not greater than 0.25-second release time.
The switch shall meet the requirements specified in table I, for the temperature-tested samples, in the
order shown (see 4.6.5.4).
3.7 Identification marking. Identification marking shall be in accordance with MIL-STD-130 (see
4.6.2).
3.8 Workmanship. Workmanship shall be of a quality which will assure a product free of pinholes,
flash, protrusions, or breaks in the rubber covering specified in MS39058 or in lead wire insulation (see
4.6.2).
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as
follows:
a. Qualification inspection (see 4.4).
b. Conformance inspections (see 4.5).
4.2 Test equipment and inspection facilities. Test and measuring equipment and inspection facilities
of sufficient accuracy, quality and quantity to permit performance of the required inspection shall be
established and maintained by the supplier. The establishment and maintenance of a calibration system
to control accuracy of the measuring and test equipment shall be in accordance with NCSL-Z540.3,
ISO-10012-1 or equivalent system as approved by the qualifying activity.
