1.0 SCOPE This Specification Control Document (SCD) defines the requirements for the Series 250 pushbutton switch assemblies and companion products. Companion products are covered by their respective SCD's. The Staco Systems Series 250 is a complete product line of high brightness light-emitting diodes (HB LED) lighted pushbutton switches and indicators. This product line conforms to the general requirements of MIL-PRF-22885, and, in matrix form, MIL-S-24317. The high-brightness LED light source is qualified for NVIS under MIL-L-85762 (when applicable), MIL-STD-3009, and MIL-PRF-22885. 2.0 APPLICABLE...

Figures 2 thru 5 depict a typical splash-proof and watertight enclosure designs, in various terminations. Each switch or indicator assembly intended for individual mount application is provided with a set of mounting hardware, which consists of a panel spacer and two mounting sleeves. These are used in conjunction with the mounting screws and cam nuts (located on two opposite sides of switch’s main body) to install the switch/indicator to the panel. Refer to Figure 6: Drip Proof (PCB Termination Version Shown, Panel Spacers and Mounting Sleeves not shown for clarity). Each splash-proof pushbutton...

3.1.2. Customized Configurations Customized configurations are unique in which they conform to a specific customer-defined configuration and/or have unique requirements for performance, marking, or both. Customized configurations shall be designed and manufactured to meet the general requirements of MIL-PRF-22885 whenever possible. However, specific customer-invoked design requirements may compromise certain performance characteristics and thus prevent total compliance with the details of the mentioned specification. 25XXXX-TAB numbers shall be used when define non-standard pushbutton switch...
