The 100SP3T2B4M7RE is a three-position sealed toggle switch featuring a single-pole double-throw (SPDT) contact configuration with gold-plated contacts for reliable electrical connection. The switch is rated for a maximum of 0.4 volt-amps (VA) at 20V (AC or DC) and is designed for 6,000 make-and-break cycles at full load. It provides an insulation resistance of 1,000 megaohm minimum and a dielectric strength of 1,000 V RMS at sea level, ensuring robust electrical isolation and safety. The switch operates across a temperature range of -40°C to +85°C and features an epoxy seal for environmental protection. This switch is commonly used in control panels, instrumentation, and consumer electronics applications where compact, sealed switching with moderate power handling is required.
