MIL-DTL-15743E
3.5.3 Wiring diagram. Where required (see 3.1), the wiring diagram shall be in accordance with MIL-E-
2036, except the plastic protective material shall conform to L-P-504 or L-P-535, as applicable. Sufficient
blank space shall be available for depicting the external switch connections after installation.
3.5.4 Local wiring. Where required (see 3.1), local wiring shall be installed by the contractor.
3.5.5 Threaded parts and fastening devices. Unless otherwise specified (see 3.1), threads for all
threaded parts and fastening devices shall be in accordance with MIL-E-917, except they shall conform to
FED-STD-H28 and shall be right hand, coarse-threaded series, unified form, class 2A or 2B conforming
to FED-STD-H28/2.
3.5.6 Welding and brazing. Welding and brazing of non-electrical parts shall be in accordance with
commercial practices and shall otherwise meet all of the requirements specified herein.
3.5.6.1 Brazing. Parts or components shall be fastened by intermittent localized brazing in such a
manner as to ensure that each enclosure assembly will not be completely soft-annealed and will not
distort or leak when subjected to the shock tests (see 4.6.6).
3.5.7 Solder and soldering flux. Solder, when used for electrical connections, shall be composition
3.5.8 Stress relief. All metals used in the switch enclosure assembly shall be treated or heat treated to
prevent deterioration or failure due to stresses or other conditions resulting from working, forming, and
similar processes during fabrication.
3.5.9 Drilling, countersinking, and tapping. Drilling, countersinking, and tapping shall be done before
plating or finish is applied.
3.5.10 Electrical creepage and clearance distances. Electrical creepage and clearance distances shall
be in accordance with MIL-E-917.
3.6 Performance requirements.
3.6.1 Dielectric withstanding voltage. For enclosed switches having electrical circuits other than
switches (see 3.1), there shall be no evidence of disruptive discharge, arcing (other than at 6 test
probes), flashover, corona (visible, audible, or smell), or breakdown when tested as specified in 4.6.2.
3.6.2 Insulation resistance. For enclosed switches having electrical circuits other than switches (see
3.1), the insulation resistance of the electrical circuits shall be not less than 10 megohms when tested as
specified in 4.6.3.
3.6.3 Mechanical operation. The enclosed rotary switches shall be mechcanically operative and shall
exhibit no sign of binding
3.6.4 Vibration. When enclosed rotary switches are tested as specified in 4.6.5. There shall be no loss
of illumination of the lamp circuit. The monitoring of switch contacts shall be part of the qualification test
