The 7101J1V3BE2 is a single-pole double-throw (SPDT) miniature rocker switch from C&K's 7000 Series, designed for vertical mounting with a V3 bracket configuration on printed circuit boards. This switch features a snap-in mounting design with an epoxy seal, accommodating panel thicknesses from 0.062 to 0.125 inches (1.57 to 3.18 mm). The switch operates with a contact rating of 0.4 VA maximum at 20 V AC or DC, and maintains contact resistance below 10 mO typical at 2-4 V DC with 100 mA current. It is rated for 40,000 electrical cycles at full load and operates reliably across a temperature range of -30°C to 85°C. The 7101J1V3BE2 is commonly used in consumer electronics, industrial control panels, and instrumentation applications where compact, reliable switching is required in space-constrained environments.
