MIL-DTL-13484G
3. REQUIREMENTS
3.1 Qualification. Switches furnished wader this specification shall be products which are authorized
by the qualifying activity for listing on the applicable Qualified Products List (QPL) at the time set for
opening of bids (see 4.4 and 6.3).
3.2 Materials. Materials shall be as specified herein and in applicable specifications and standards.
3.2.1 Dissimilar metals. Except where necessary to complete an electrical circuit, contact between
dissimilar metals which would encourage galvanic action shall be avoided (see 4.6.1).
3.2.2 Recycled, virgin, and reclaimed materials. Recycled, recovered, or environmentally preferable
materials should be used to the maximum extent possible, provided that the material meets or exceeds
the operational and maintenance requirements, and promotes economically advantageous life cycle costs
(see 6.4.2).
3.2.3 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and
externally. Tin content of switch components and solder shall not exceed 97 percent, by mass. Tin shall
be alloyed with a minimum of 3 percent lead, by mass (see 6.8)
3.3 Design and construction. Switch dimensions, construction and requirements shall be as
3.4 Physical requirements.
3.4.1 Shock. While carrying a rated resistive load current of 15 amperes, the switch shall not open or
do., during shock testing as specified in MIL-STD-202, method 213, test condition I. After the shock test,
3.4.2 Vibration. While carrying a rated resistive load current of 15 amperes, the switch shall not open
or close during vibration testing as specified in 4.6.3.2. After the vibration test, the switch shall meet the
3.4.3 Lead connections. Lead connections to the switch body shall withstand a force of 110 Newton
(N), applied in specified directions, without damage. Subsequently, the switch shall meet the
3.4.4 Physical characteristics. The switch shall actuate with 4.5 to 9.0 Newton (N) of force applied
within 3 mm of center of switch button. Other physical characteristics shall be as follows (see 4.6.3.4):
Release force - 1.7 newton, minimum.
Release time - 0.25 second, maximum.
Pretravel - 0.38 mm, minimum.
Overtravel - 0.38 mm, minimum.
Movement differential - 0.26 mm, maximum.
3.5 Electrical requirements.
3.5.1 Current rating. The current rating shall be 7.5 amperes lamp load, 7.5 amperes inductive load
(L/R ratio 0.026), and 15 amperes resistive load (see 4.6.4.1).
3.5.2 Contact voltage drop. With switch contacts closed and a rated resistive load current of 15
amperes applied, the measured allowable voltage drop shall not exceed 150 millivolts, except as
