The 7211MD9ABE is a miniature toggle switch from the C&K 7000 Series designed for reliable switching control in compact applications. This 3-pole double-throw (3PDT) switch features solder lug termination with epoxy seal protection, providing robust electrical connections suitable for PCB assembly. The switch operates across a temperature range of -30°C to 85°C and delivers contact resistance below 10 mO typical at 2-4 V DC with 100 mA, ensuring low-loss signal transmission. With an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms at sea level, this switch meets stringent electrical isolation requirements. The 7211MD9ABE is commonly used in industrial control panels, telecommunications equipment, and consumer electronics where reliable multi-pole switching and compact form factor are essential.
