MIL-DTL-3950/14A
REQUIREMENTS:
Dimensions and configuration: See figures 1, 2, and 3.
Strength of toggle lever, pivot, and lever stop:
The switch shall operate mechanically and electrically at a maximum load of 6 volts dc, 100
milliamperes after the following test:
a. A 25-pound load shall be applied to the rocker button for one minute under each of the
following conditions:
(1)
Perpendicular to the face of the rocker button near the .73R (see figures 1 and 2).
Load to be applied toward the base.
(2)
Coaxial with centerlines of the switch. Load to be applied toward the base.
Strength of mounting means:
Switches shall be mounted on a metal panel using normal mounting means and hardware. A torque
of 5 pound-inches shall then be applied to the mounted switch body. When switches are tested as
specified, there shall be no loosening of mounting hardware or other mechanical damage.
Mechanical endurance: Temperature extremes, -55°C + 0°C, -4°C to +71°C +4°C, -0°C.
Thermal shock: Temperature extremes, -55°C + 0°C, -4°C to +71°C +4°C, -0°C.
Weight:
One pole: .10 pound maximum.
Two pole: .15 pound maximum.
Four pole: .22 pound maximum.
Qualification: The strength of mounting means test shall be substituted in place of the strength of
mounting bushing test in the inspection sequence.
Group submission: The basic switches (to be submitted to all applicable tests) are M3950/14C35F1W
and M3950/14C23S2R. In addition, the following additional switches shall be submitted to examination
of product and switching characteristics:
M3950/14A27F1B
M3950/14B28S1C
