The 7103SCWZQE is a single-pole, on-off-on miniature toggle switch from the C&K 7000 Series, featuring SPDT (single-pole, double-throw) configuration with three stable positions. The switch utilizes copper alloy contacts with gold plate over nickel plate, providing reliable electrical performance with contact resistance below 10 mO typical at 2–4 V DC and 100 mA. It is rated for 5 amps at 120 V AC or 28 V DC, with an electrical life of 40,000 make-and-break cycles at full load, and operates reliably across a temperature range of -30°C to +85°C. The switch features an epoxy terminal seal, brass hardware with nickel plating, and is compatible with standard PCB cleaning methods. This switch is ideal for applications requiring compact, reliable switching in control panels, instrumentation, and consumer electronics where space is limited and durability is essential.
