DA221-PB-B is a D-Series single pole compact high current toggle switch designed for applications with back panel size constraints. This switch features an On-None-Off circuit configuration with a paddle actuator style, black actuator color, black bushing color, and .250 tab (Q.C.) terminals. It offers ratings of 20A at 125VAC, 10A at 250VAC, and 1½ HP at 125-250VAC, with self-cleaning contacts and economical double insulated all nylon construction. The switch provides a dielectric strength of 1000V between live to dead metal parts and opposite polarity, an electrical life of 25,000 cycles, and operates within a temperature range of 32°F to 185°F (0°C to 85°C). Common applications include environmental controls, marine, food service, and vacuum cleaners where stringent current carrying requirements are needed.
