7、sions and configuration: See figure 1. Material and finish: Bushing shall be brass, nickel plated. Toggle lever shall be brass, bright chrome plated. Frame shall be stainless steel. The contacts shall be gold plate over nickel over silver over brass. Mounting hardware: Each switch shall be supplied
8、with one hexagon nut and one internal-tooth lockwasher in accordance with the appendix of MIL-DTL-83731, one locking ring (see figure 3), and one panel seal (see figure 3). The panel seal shall be silicone rubber. Weight: .024 pound maximum. Electrical ratings: See table I. Strength of terminals: Me
9、thod 211 of MIL-STD-202, test condition A. The applied force shall be one pound. Strength of toggle lever, pivot, and lever stop: Test (a) shall use a 10 pound load; test (b) shall use a 8 pound load. Dielectric withstanding voltage: Test at atmospheric pressure only. Mechanical endurance: 20,000 cy
10、cles of operation. One-half of the cycles shall be at -25C +0C, -4C, while the other half of the cycles shall be at + 71C +4C, -0C. Electrical endurance, electrical overload, electronic logic, and temperature rise: Multi-pole switches are to be tested with a load on each pole and with the same polar
11、ity on adjacent poles in accordance with figure 2. FIGURE 2. Test circuit.

13、L-DTL-83731 electrical endurance. Fifty percent of test cycles at room ambient conditions. Fifty percent of test cycles at 71C, +4, -0C. No “sticks” or “misses” allowed. Inductive load (dc and ac): 10,000 cycles. Altitude testing not applicable. Lamp load: Switches shall make and break the rated lam
14、p load for 10,000 operating cycles. Intermediate current: Not applicable. Short circuit: Use 100 amperes at 28 V dc. Flux sealed: The sealing is obtained when the base is sealed to prevent flux from entering the switch case during the wave soldering process. Flux seal test: Three additional switches
15、 shall be tested as follows during qualification and group B inspection: Measure and record initial contact resistance. Place switches, terminals down, into a shallow pan. Pour flux at 80F 5F, type RMA of J-STD-004, specific gravity 0.896, into pan without splashing until level of flux is approximat
16、ely 1/16 inch above the bottom of the plastic switch case and let switches soak for 10 minutes. Remove switches from flux, clean with flux cleaning solvent and immediately put into oven for drying at 175F for two hours. After switches have cooled to room temperature, repeat initial measurement. Cont
17、act resistance shall not increase by more than 10 milliohms over the initial reading. Disassemble and visually examine the contact area for evidence of flux. Any evidence of flux shall be cause for rejection. Sand and dust: Not applicable. Explosion: Not applicable. Part number: The part number shal
