2.1.1
Compact bodies can be specified for Standard Square or Large Rectangular caps and must be specified to accommodate an unsealed or sealed cap installation.

When specified, a sealed body is supplied with a dripproof spacer and dripproof flange that accepts the seal of a sealed cap. 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.
Configurations (Switches and NEXSYS Components)
VIVISUN® Compact bodies have two available “positions” to accommodate electromechanical switch poles and NEXSYS® components. Positions are identified on the exterior of the switch body and the connector plug as Poles A and B. Electromechanical switches each occupy a single switch pole. In Compact bodies, NEXSYS components can also occupy a single pole position. As shown in Figure 2.1.1-B, there are five specific build configurations that reflect the possible arrangements of switches and NEXSYS components in a Compact Body. The assignment of selected components to specific pole positions is done at the time of final part configuration. An “open” spacer will be placed in any unused pole position.

Compact bodies without NEXSYS components (only electro-mechanical switches and/or open spacers) have two keying slots and use connector plug (P/N 18-200) for wiring termination. Compact bodies with one or more NEXSYS components have only one keying slot and use a specially keyed connector plug (P/N 18-442) for wiring termination. See Section 2.4 for complete description of Compact body (14 socket) connector plugs.
See Section 2.4 for installation instructions, and refer to Appendix B for various mounting options, including the proper usage of the optional mounting spacer provided with Standard Square bodies.
