The 7105P4D9ZBE is a miniature toggle switch from the C&K 7000 Series designed for single-pole double-throw (SPDT) switching applications. It features a 1/4-40 UNS-2A threaded bushing with keyway, epoxy seal, and PC board through-hole terminations with 0.080 inch terminal width. The switch operates over a temperature range of -30°C to 85°C and provides contact resistance below 10 mO typical at 2-4 V DC with 100 mA. With an electrical life of 100,000 make-and-break cycles at full load and insulation resistance of 10? O minimum, this switch is suitable for industrial control panels, instrumentation, and consumer electronics requiring reliable switching in compact form factors.
