MIL-DTL-3950J
4.8.6 Strength of toggle lever, pivot, and lever stop (see 3.6.5). The switch shall operate mechanically
and electrically at a maximum load of 6 volts dc, 100 milliamperes after the following tests:
a. A 25-pound load shall be applied to the tip of the actuating lever for one minute under each of the
following conditions:
(1) Perpendicular to the lever axis and parallel to the line of lever travel at each end position
of the lever. For lever-lock types, the types shall be conducted at each fixed position of
the lever.
(2) Perpendicular to the lever axis and perpendicular to the line of travel at each lever
position.
(3) Coaxial with the lever axis away from the lever pivot, throughout the entire range of lever
travel.
b. A 25-pound load shall be applied to the tip of the actuating lever, coaxial with the lever axis and
toward the lever pivot, throughout the entire range of lever travel. For lever-lock types, this test is
the entire range of lever travel. For lever-lock types, this test is only applicable to those changes
in lever from its detent position.
4.8.7 Strength of mounting bushing (see 3.6.6). Bushing-mounted switches shall be mounted on a
metal panel using normal mounting means and hardware. A torque of 25-pound-inches shall be applied
to the mounting nut on switches with 15/32-inch diameter bushing or larger and a torque of 15-pound-
inches shall be applied to the mounting nut on smaller size bushing. With the mounting nut tightened
using a maximum torque of 5 ounce-inches, a torque of 5 pound-inches shall then be applied to the
mounted switch body.
MIL-STD-202; the following details and exceptions shall apply:
a. Measurements shall be made between the terminals of the contacts of the same pole forming a
switching circuit. Measurements shall be made for each pole of multipole switches.
b. Test circuit - 100 milliamperes.
c.
Open-circuit voltage - 2 volts dc to 6 volts dc.
d. Number of activations prior to measurement - 3.
e. Number of test activations - 3.
f.
Number of measurements per activation - 1.
