The 7211J3ZQE2 is a miniature rocker switch from the C&K 7000 Series, configured as a single-pole double-throw (SPDT) switch with a lever handle and metal frame in black color. This switch features PC thru-hole termination suitable for printed circuit board mounting and is rated for 0.4 VA maximum at 20 V AC or DC with B contact material. The switch operates reliably over a temperature range of -30°C to 85°C and maintains contact resistance below 10 mO typical at 2-4 V DC with 100 mA current. With an electrical life of 40,000 make-and-break cycles and dielectric strength of 1000 Vrms minimum at sea level, this switch is well-suited for consumer electronics, industrial control panels, and appliance applications requiring compact, reliable switching functionality.
