Cole Hersee Sealed Rocker Switch Non-Illuminated SPST On-Off 2 Screw

The Cole Hersee Sealed Rocker Switch Non-Illuminated SPST On-Off 2 Screw (model 56027-01-BP) is a heavy-duty electrical control switch engineered for marine, automotive, and industrial applications where moisture and spray exposure demand sealed construction. This single-pole, single-throw switch combines IP66-rated water resistance with robust electrical ratings, making it ideal for environments where standard rocker switches would corrode or fail.

The switch delivers 20 amps at 12V DC and 10 amps at 24V DC, supporting the majority of 12-volt vehicle and equipment circuits as well as dual-voltage marine and industrial systems. Its IP66 sealing rating indicates complete dust protection and resistance to high-pressure water jets—critical for boat bilge systems, off-road vehicle lighting, water pumps, and outdoor equipment panels. Two brass screw terminals provide secure, corrosion-resistant connections without the need for solder or crimps, simplifying installation and reducing connection failures over time. The non-illuminated design keeps the switch simple and cost-effective for applications where status indication is handled separately.

This switch serves marine electricians, fleet maintenance technicians, equipment manufacturers, and DIY builders working with boats, RVs, agricultural machinery, and industrial control panels. Cole Hersee is recognized for manufacturing reliable electrical components in harsh-duty markets, and this sealed rocker switch is a standard replacement part in marine and off-road electrical systems. The compact dimensions (3 × 2 × 6 inches) and lightweight design (0.1 lbs) fit standard panel cut-outs without requiring custom fabrication.
