MIL-DTL-13625F
3.4.5 High voltage. When tested as specified in 4.5.6.5, the switch shall evidence no sparking, arcing,
burning, smoking, charring, cracking, loosening, rupturing, or other damage to the insulation.
3.4.6 Endurance. When tested as specified in 4.5.6.6, the switch shall show no evidence of
mechanical or electrical failure. After the test, the contact voltage drop, measured as specified in the
applicable portions of 4.5.6.3 and determined as specified in 4.5.6.3.2, shall not exceed 120 millivolts and
3.5 Environmental.
3.5.1 Salt fog (corrosion). When tested as specified in 4.5.7.1, the switch shall evidence no corrosion
3.5.2 Fungus. When tested as specified in 4.5.7.2, the switch shall evidence no fungus growth
3.5.3 Waterproofness. The switch assembly shall evidence no leakage and shall be mechanically and
electrically operable during and subsequent to submersion, when subjected to test specified in 4.5.7.3.
3.5.4 Extreme temperatures. When tested as specified in 4.5.7.4, the switch shall operate in a
temperature range of -65F through +165F. While at -60F 5F, the minimum force required to actuate
or close the switch shall be no more than 40 percent higher than the average actuation force previously
measured at room temperature (see table II, specimens 3 and 4). The switch shall subsequently meet
the requirements of 3.4.2 and 3.4.3.
3.6 Physical.
3.6.1 Shock. When tested as specified in 4.5.8.1, the switch shall evidence no mechanical or electrical
malfunction (opening or closing of circuits). After shock test, switches shall have no loosened, distorted,
or broken parts.
3.6.2 Vibration. When tested as specified in 4.5.8.2, the switch shall evidence no mechanical or
electrical malfunction (opening and closing of circuits). After vibration test, switches shall have no
loosened, distorted, worn, or broken parts and shall subsequently meet the requirements of 3.4.2 and
3.6.3 Terminal strength. When tested as specified in 4.5.8.3.1, terminals of switches with receptacle
(mating) connectors shall withstand a force of 40 pounds. When tested as specified in 4.5.8.3.2, the
terminals and lead connections of switches with permanently attached leads shall withstand a force of 40
pounds. When tested as specified in 4.5.8.3.3, switches with screw type terminals shall withstand the
minimum torque necessary to seat the outermost nut properly. No switch, regardless of terminal
construction, shall have any deformation of more than .062 inch (1.57 mm) or any rotation of more than
15 after the test. Each switch, regardless of terminal construction, shall subsequently meet the
requirements of 3.4.3.
3.7 Finish. Cleaning, pretreatment, priming, and painting shall conform to best commercial practices
(see 4.5.10).
3.8 Marking.
3.8.1 Identification marking. Identification marking shall be in accordance with MIL-STD-130 and as a
minimum shall include the following (see 4.5.10).
Applicable Military Standard or drawing number
Manufacturer's Name or Identification
Date of Manufacture (month, year; e.g., June 85)
