KCD-4 Rocker Switch 4-Pin On/Off Red Illuminated 30A (DPST)

This is the heavy-current member of the KCD-4 family, rated at 30A 250V AC — roughly double the standard KCD-4 — and built with silver contacts rather than plain copper to survive the arcing that comes with switching that kind of load. A red neon indicator shows the circuit state, and the four solder or male spade terminals break both supply lines together in a DPST arrangement. Marked CE and CQC with a T85/55 temperature rating and 10,000-cycle electrical endurance, it is intended for genuinely demanding duty: welding plants and arc welding machinery, submersible pumps and industrial water pumping control panels, high-power electric motors and industrial supplies, and heavy home appliances and distribution panels.
