MIL-DTL-3786/3G
REQUIREMENTS:
Dimensions and configurations: See figures 1 and 2.
Angle of throw: 30°, 36°, 45°, 60°, and 90°.
Terminals: The terminal tabs shall be bent at an angle of 60 ±15 degrees from the plane of the
section. When flat terminals are required, the dimensions shall be as shown on figure 1.
Rotational torque: The minimum and maximum values of torque determined for shaft rotation shall be
within the limits specified in table I. The rotational torque shall not change more than ±50 percent from
its initial value and shall be not less than the minimum torque specified.
