The 641NH is a double-pole toggle switch with an insulated black polyamide lever designed for high-amperage panel-mount applications. It features a 26° angle of throw with ON-OFF-ON electrical function, providing robust switching capability with a maximum current rating of 15 A at 250 VAC and 10,000 electrical life cycles at full load. The switch incorporates a polyester UL94-V0 case, silver/nickel alloy contacts, and brass nickel-plated bushing, with an operating temperature range of -20°C to +55°C. It meets UL, CSA, and NF-VDE (EN 61058-1) approvals and offers excellent insulation resistance of 1,000 MO minimum at 500 VDC and dielectric strength of 2,000 Vrms between terminals. The 641NH is ideal for industrial control panels, machinery, and equipment requiring reliable high-current switching with safety certifications.
