The 100SP5T2B4M6RE is a Series 100 miniature toggle switch featuring a single-pole double-throw (SPDT) switching function with gold-plated contacts and epoxy seal at the base of the terminal. This switch is designed for panel mounting with a 1/4-inch bushing and PC-mount termination (M6 option), providing robust electrical performance with contact resistance of 10 mO maximum at 2-4 VDC and 100 mA. The switch operates reliably over a temperature range of -30°C to +85°C with an insulation resistance of 1,000 MO minimum and dielectric strength of 1,000 V RMS at sea level. With a life expectancy of 40,000 make-and-break cycles, this miniature toggle switch is well-suited for telecommunications, instrumentation, networking, and medical equipment applications where space constraints and reliable switching performance are critical requirements.
