MICRO SWITCH Commercial-Grade Toggle Switches 005435 AT Series Issue 1 Datasheet FEATURES Assemblies available as MIL-PRF-8805 qualified or the individual basic switches with UL, CSA, and CE certification 2- or 3-position, momentary and maintained action Up to 10 SPDT precision basic switches Short behind-panel depth Choice of 14- or 15/32-inch bushings Silver or gold contacts Lever lock options Toggle lever and panel seal options Electrical connections: screw, solder, quick connect (blade), and preleaded DESCRIPTION POTENTIAL APPLICATIONS Honeywells MICRO SWITCH AT toggle switches provide Aircraft (commercial and military) a compact multi-pole toggle switch with a long history of Military ground vehicles successful performance, exceeding 50 years. The AT Toggle Flight controls Switch Series is available as a 1-, 2-, 3-, 4-, 6-, 8-, or 10-pole Vehicle panel controls design for a wide range of applications with a metal toggle lever, metal bushing, and metal housing for durability. Select AT PORTFOLIO Series are qualified to MIL-PRF-8805 for military applications. Honeywell offers six series of MICRO SWITCH toggle switches For applications which do not require a military approved switch, including the TL Series, NT Series, TS Series, TW Series, and ET there are other AT Series switches for commercial and industrial Series. applications. Options for the AT Series include panel seals and lever-to- bushing seals. These options enhance product performance where environments of dust or water spray could be present in the application. Complementing the product offering, MICRO SWITCH AT toggle switch assemblies are available with individual poles (basic switches) which are UL, CSA, and CE certified. VALUE TO CUSTOMERS Multi-pole, multi-throw circuitry (up to 10 pole) for controlling independent circuits or providing redundant circuit capability Flexible insulators between poles minimize electrical bridging MIL-PRF-8805 qualified switches Reduces service costs Extends equipment life Front of panel sealing available DIFFERENTIATION Only manufacturer with 10-pole circuitry Utilizes proven and reliable snap-action switch design Sensing and Productivity SolutionsMICRO SWITCH Commercial-Grade Toggle Switches, AT Series Table 1.
