KCD-4 Rocker Switch 4-Pin On/Off Black (DPST)

The KCD-4 in its plain black 4-pin form is the workhorse of the range — a double-pole single-throw rocker that breaks both supply lines at once rather than switching a single pole, which is the correct arrangement for isolating mains-fed equipment. The larger KCD-4 body carries 16A at 250V AC and 20A at 125V AC, well above the KCD-1 sizes, and its snap-in housing drops into a standard rectangular cut-out without a nut or bracket. Clear I and O markings on the actuator keep the switch state unambiguous. It suits power distribution units and benchtop supplies, household appliances and kitchen electronics, industrial control panels, and custom enclosures and amplifier builds.
