1.1
For Standard Square and Large Rectangular caps, the dimensions and viewable area of a cap are based on its specification as unsealed or sealed. Sealed caps prevent the ingress of water, sand, or dust through the mounting cutout in the panel.
For each of the four available cap sizes shown in Figure 1.1.0-A, there are three body sizes.
See Section 2.0 for a complete description of body types, including images and dimensions of caps when used in conjunction with each body type. Bodies that are specified to be used with an unsealed cap are provided with a standard panel spacer. Bodies that are specified to be used with a sealed cap are provided with a specific panel spacer and mounting flange designed to accept the seal that is permanently affixed to the cap.
Caps are mechanically and electrically separate from the body. Caps can be ordered separately, or can be purchased with a switch body as part of a switch assembly.

When installed in a switch body, caps are retained by means of a metallic retainer which is permanently mounted in the switch body housing. Cap material and weight information is provided in Section 3.3. Cap installation and removal information is provided in Section 3.4.
When specified, a sealed cap is supplied with a dripproof seal that mates with the dripproof flange provided with a sealed body. Sealed switches do not allow leakage of water through the seal when subjected to the splashproof, watertight, and dripproof sealing test defined in MIL-PRF-22885F paragraph 4.7.20.1 - .3 and MIL-STD-108. Sealed switches also meet the sand and dust test defined in MIL-PRF-22885F paragraph 4.7.26.
