MIL-PRF-22885/111B
Shock:
All switch types: Method I (75 g).
Switch types III and VI (sealed switches): High impact shock in accordance with MIL-S-901, grade A, class
II (for deck-mounted equipment) when attached to the anvil plate of the shock machine by means of
standard mounting figure 11-C with simulated console, which provides resilient mounting typical of
in-service use within "deck-mounted" electronic cabinets or panels. These units are not recommended for
direct "hull mounted" applications.
Salt spray: Test condition A (96 hours).
Sand and dust: Applicable.
Terminal strength:
Solder terminals, applied force and direction of force: 3 pounds perpendicular to the long axis, and 5
pounds parallel to the long axis.
Electrical endurance: 25,000 cycles at the following electrical ratings:
Silver contacts:

Low-level life: Applicable to switches with gold plated contacts.
Intermediate current: Applicable to switches with silver contacts.
Mechanical endurance: 100,000 cycles consisting of 5,000 cycles of operation at -55°C ±2°C, 10,000 cycles
of operation at +85°C ±2°C, and 85,000 cycles of operation at room temperature.
Illuminated color and luminance: See table I.
