E103J1V3BE2 is a sealed miniature rocker switch featuring single-pole double-throw (SPDT) functionality with vertical V3 termination for PC board mounting. The switch is sealed against solder and cleaning process contaminants and offers ESD resistance rated at 15,000 V DC maximum at sea level from actuator to terminals. It provides a contact resistance below 10 mO typical at 2–4 V DC with 100 mA, and an insulation resistance of 10? O minimum. The switch is rated for 40,000 make-and-break cycles at full load with a dielectric strength of 1000 Vrms minimum at sea level. The rocker actuator, case, and bushing are UL 94V-0 rated and RoHS compliant. This sealed switch is ideal for telecommunications, instrumentation, and computer peripheral applications where protection from environmental contaminants and reliable switching performance are essential.
