The 7208J21ZQE22 is a miniature rocker switch from the C&K 7000 Series featuring a DPDT (double-pole double-throw) switching function with a J21 lever actuator and black frame. This switch is designed for rear-mount panel applications with PC thru-hole termination, supporting panel thicknesses from 0.062 to 0.125 inches. The switch operates over a temperature range of -30°C to 85°C and provides contact resistance below 10 mO typical at 2-4 V DC with 100 mA, along with an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms minimum at sea level. With an electrical life of 40,000 make-and-break cycles at full load and contact ratings of 5 amps at 120 V AC or 28 V DC, this switch is well-suited for industrial control panels, consumer appliances, and instrumentation applications requiring reliable switching performance.
