MIL-PRF-22885H
3.6.10 Panel seals. Panel seals shall be selected to enable the switch to meet performance requirements of this
specification. Additional information and guidance on rubber material is provided in 6.14.
3.7 Solderability (applicable to solderable terminals). When switches are tested as specified in 4.7.2, the criteria
for acceptable solderability shall be in accordance with method 208 of MIL-STD-202.
3.8 Resistance to soldering heat (applicable to switches with solderable terminals). When switches are tested as
specified in 4.7.3, there shall be no deformation or other damage at the conclusion of the test sequence.
3.9 Contact resistance (unless otherwise specified, see 3.1). When measured as specified in 4.7.4.1, the contact
resistance shall not exceed 25 milliohms. When measured as specified in 4.7.4.2, the lamp contact resistance shall
not exceed 1.0 ohm. After electrical endurance, the contact resistance shall not exceed 1 percent of the load
impedance using the electrical parameters of the electrical endurance test load. Lamp contact resistance is not
applicable after electrical endurance.
3.10 Contact bounce (when specified). When switches are tested as specified in 4.7.5, the contact bounce shall
3.11 Operating characteristics. When switches are tested as specified in 4.7.6, the operating characteristics shall
be as specified (see 3.1 and 6.2). Unless otherwise specified, switch action will be break before make (see 3.1 and
6.2).
3.12 Coincidence of operating and releasing points (when specified) (applicable to multipole switches). When
switches are tested as specified in 4.7.7, all poles shall have actuated (transfer of contacts) within the limits specified
3.13 Permanency of marking (when specified). Following the test specified in 4.7.8, all required markings shall be
legible (see 3.45).
3.14 Terminal strength. When switches are tested as specified in 4.7.9, there shall be no short circuiting,
breakage, loosening, rotation of terminals, or damage which will interfere with the electrical or mechanical
performance of the switch.
3.15 Strength of actuating means. When switches are tested as specified in 4.7.10, there shall be no damage
which will interfere with the electrical or mechanical performance of the switch. The operating characteristics shall be
3.16 Strength of actuator (bushing mounted switches). Actuators on bushing mounted switches, which receive
either snap-in or screw-in pushbuttons, shall exhibit no electrical discontinuity or mechanical loosening of the actuator
when tested as specified in 4.7.11. The operating characteristics shall be as specified (see 3.1 and 6.2).
3.17 Strength of mounting bushing (applicable to threaded mounting bushings)(see 3.1 and 6.2). When switches
are tested as specified in 4.7.12, there shall be no damage to the switch or loosening or twisting of the bushing
3.18 Lens orientation. When screw-in orientable type lenses are specified (see 3.1 and 6.2), the lens shall be
capable of rotating a minimum of 350°, after installation, when subjected to the tests specified in 4.7.13. When
snap-in pushbuttons are specified (see 3.1 and 6.2), the lens shall not rotate more than 10 degrees between stops,
after installation, when subjected to the tests specified in 4.7.13. There shall be no damage to the lens indexing
mechanism.
3.19 Thermal shock. When switches are tested as specified in 4.7.14, there shall be no mechanical or electrical
damage, or loosening of fastening devices. There shall be no discoloration or deformation of the lens.
