The 7101MDCQE is a single-pole double-throw (SPDT) miniature toggle switch from the C&K 7000 Series, designed for compact electronic applications requiring reliable switching functionality. This switch features a contact rating of 0.4 VA maximum at 20 V AC or DC, with contact resistance below 10 mO typical at 2-4 V DC and 100 mA. The switch is rated for 100,000 make-and-break cycles at full load, with an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms minimum at sea level. It operates reliably across a temperature range of -30°C to +85°C and includes an epoxy seal for environmental protection. The 7101MDCQE is commonly used in instrumentation, control panels, and consumer electronics where space constraints and long-term reliability are essential.
