The III-43405000 is an H/I-Series toggle switch designed for general-purpose industrial control and automation applications. It features electrical ratings up to 17A 125VAC, 10A 250VAC, and 3/4 HP 125-250VAC with options for 1, 2, or 3 phase configurations. The switch offers 50,000 cycles of electrical life under maintained operation and 25,000 cycles for momentary operation, with a mechanical life rating of 100,000 cycles. Operating temperature range spans 32°F to 185°F (0°C to 85°C), and dielectric strength is rated at 1000V UL/CSA between live and dead metal parts. Available with multiple actuator styles (bat, paddle), bushing lengths, and termination options (solder lug, 0.250 tab, screw, wire leads), this toggle switch is well-suited for food service, generator, industrial control, and office automation markets, as well as low voltage DC applications.
