Enclosure design: 4 (resilient). All entrances to the switch cavity except through the actuator bushing shall be sealed
by fusion of glass to metal, metal to metal, or ceramic to metal and the lead wires shall be potted to provide stress
relief.
Temperature characteristics: 1 (-55C to +85C).
Shock: 75 g's in accordance with MIL-STD-202; method 213, test condition H.
Vibration grade: 1 (10 to 500 Hz).
Material:
Lock washer: Corrosion-resistant steel or plated to resist corrosion.
Hex nut and locking nut: Corrosion resistant or plated to resist corrosion.
Plastic: Type CFG, in accordance with ASTM-D548, may be used internally.
Finish: Switch housing shall be processed to resist corrosion.
Operating characteristics: See table I.
Fluid resistance: Except for the cut end of the lead wire, switches shall be submerged in each of the following fluids
for 2 to 2.5 minutes, which shall consist of one cycle (one cycle is 10 to 12.5 minutes total). Each switch shall be
subjected to three cycles.
a.
Turbine fuel (MIL-DTL-5624).
b.
Hydraulic fluid (SAE AS1241A).
c.
Coolanol 1/ (MIL-PRF-87252).
d.
Ethylene glycol (ASTM -E1119).
e.
Lubricating oil (MIL-PRF-7808).
After each immersion, the excess fluid shall be blown off the external surfaces of the switch with an air jet. Following
the third cycle, the switch shall be subjected to and shall meet the requirements for dielectric withstanding voltage,
insulation resistance, operating characteristics, and seal test.
Contact resistance: Not applicable.
Insulation resistance: 100 megohms minimum.
Dielectric withstanding voltage:
Sea level: 1,000 V rms.
Altitude: 300 V rms.
Mechanical endurance: 25,000 cycles.
Electrical endurance: 25,000 cycles.
