MIL-PRF-22885/108E
NOTES:
1. Dimensions are in inches.
2. Metric equivalents are given for general information only.
3. Unless otherwise specified, tolerances are ±.010 for three place decimals and ±.03 for two place
decimals.
4. The mounting sleeve shall not exceed .760 square and shall be reversible so as to be usable with
or without the mounting spacer. In either case, the switch shall accommodate mounting to panels
from .032 to .187 thick.
5. A mounting spacer is supplied with each switch unit for SAE-AS7788 panel requirements and
places the mounting flange flush with the top of a .235 thick edgelighted panel.
6. Spacer is to be used only for edgelighted panels, discard otherwise.
7. Pushbutton cap shall be designed to prevent incorrect insertion into switch housing.
8. Pushbutton cap shall be held captive to switch body by retaining element to prevent accidental
interchange, but shall allow replacement of the lamps.
9. The Common Termination System (CTS) connector shall be designed and constructed to meet
the performance requirements of this document. These items, M22885/10818200 for 2 pole
switches and M22885/108C8240 for 4 pole switches, shall be acquired from a source listed on
QPL-22885.
10. The CTS connector shall be removable from the switch housing to allow the housing to be
mounted separately. The connector may be wired during harnessing operations, allowing bench
testing without the need of the switch housing.
11. The CTS connector shall be considered as a connector plug that may be separated from the
switch housing for the convenience of installation.
12. The CTS connector shall be removable from the switch body by use of a M22885/108T8234 CTS
module extraction tool (see figure 10). This item shall be acquired from a source listed on QPL-
22885.
13. The CTS connector shall be capable of receiving SAE-AS39029/22-192 socket contacts crimped
to a 20, 22, or 24 gauge wire.
14. The CTS connector shall be capable of having the socket contacts inserted or removed using an
M81969/14-10 contact insertion/removal tool.
15. Exact shape of switch is optional provided dimensions specified are not exceeded.
16. Terminals and basic switch identification shall be permanently marked as shown on figures 7 and
9.
