Product Overview: Big Red 4-Pin Rocker Switch (DPST)
The Big Red 4-Pin Rocker Switch is a heavy-duty power control switch designed for high-current applications. Featuring an integrated Neon or LED indicator, it provides clear visual confirmation when the circuit is active. This switch is commonly used in power strips, industrial machinery, and home appliances as a main power toggle. Its DPST (Double Pole Single Throw) configuration allows it to disconnect both the “Live” and “Neutral” wires simultaneously for enhanced safety.
