LT-1511-110-012 is a single-pole illuminated toggle switch from Carling Technologies' LT-Series, featuring a .250 tab quick-connect (QC) termination and On-None-Off circuit configuration. The switch is rated for 10A at 250VAC, 15A at 125VAC, 3/4 HP at 125-250VAC, and 15A at 12-28VDC, with a 12-volt incandescent lamp providing independent illumination. It incorporates neoprene bushing seals for dust and moisture protection, a dielectric strength of 1000V between live and dead metal parts, and an electrical life of 50,000 cycles in maintained operation or 25,000 cycles in momentary operation. The switch operates reliably across a temperature range of 0°C to 85°C (32°F to 185°F), making it suitable for marine and transportation applications where robust, sealed switching with visual feedback is essential.
