The 7103K2ZQE is a single-pole double-throw (SPDT) miniature toggle switch from the C&K 7000 Series, designed for applications requiring reliable ON-OFF-ON switching functionality. This switch features a contact rating of 0.4 VA maximum at 20 V AC or DC, with contact resistance below 10 mO typical at 2–4 V DC and 100 mA. The switch offers an electrical life of 40,000 make-and-break cycles at full load, operates reliably across a temperature range of -30°C to 85°C, and maintains an insulation resistance of 10? O minimum with a dielectric strength of 1000 Vrms minimum at sea level. The 7103K2ZQE is RoHS compliant and features an epoxy seal for environmental protection, making it suitable for industrial control panels, consumer electronics, and instrumentation applications where compact, durable switching is required.
