3、 2 NOTES: 1. Dimensions are in inches. 2. Metric equivalents are given for general information only. 3. Unless otherwise specified, tolerance is .015 (0.38 mm). 4. The number of sections is as selected from table III. 5. Nonturn device as shown is not applicable to S construction switches. 6. Inner
4、shaft stop strength 4 inch-pounds. Outer shaft stop strength 15 inch pounds. 7. Shaft-flat angle A is the angle between a line through the center of the shaft and center of the nonturn device, and another line through the center of the shaft and perpendicular to the shaft flat. For construction S sw
5、itches, the bushing flat is the nonturn device. Angle A is 270. 8. Shaft shown in maximum counterclockwise position for switches with stops, and with switch in position number 1 for switches without stops. 9. Front plate design optional provided it falls within the maximum outside diameter of the se
6、ction dimension referenced. 10. Terminal tabs may be bent to the rear at an angle up to 75 from the plane of the section. 11. Marking plate is included with all switches. FIGURE 1.

15、erature-life characteristic and shock type (see table I) Insulation material and angle of throw (see table II) Poles per deck and number of positions (see table III) Number of decks and switching characteristics (see table IV) Pins shall be generated only to identify switches shown on figure 2. Acqu
16、iring switches not identified by military pins shall be in accordance with the ordering data of MIL-DTL-3786. Application. To conserve material, space, and weight, the following is suggested: Two-position and three-position switches with 30 angle of throw should be four poles per deck. Four-position
17、 switches with 30 angle of throw should be three poles per deck. Five- and six-position switches with 30 angle of throw should be two poles per deck. Two-, three-, four-, and five-position switches with 36 angle of throw should be two poles per deck. Two-, three-, and four-position switches with 45
18、angle of throw should be two poles per deck. Two- and three-position switches with 60 angle of throw should be two poles per deck. M3786/5-ADEC identifies a rotary switch of construction type N, temperature-life characteristic B, shock types H and M, ceramic or glass bonded mica insulation material,
19、 36 degree angle of throw, 1 pole per deck, 5 positions, 2 decks, and nonshorting switching characteristic.
