It is designed as a direct equivalent for the Mercury 87-17009A5 switch, making it a straightforward replacement when an original switch fails or needs upgrading. The switch operates on a 12-volt electrical system and uses a normally-open contact design with six color-coded wire leads that are potted for protection against moisture and vibration, a common failure point in marine environments.\u003c\/p\u003e\u003cp\u003eConstruction is polyester and plastic, with a hex black plastic face nut for panel mounting and no back-up nut required, simplifying installation from the front side of the dash or console. The switch is short in length, requiring only 5\/8 inch of maximum panel thickness, which allows it to fit tight helm layouts. Contact points are stainless steel for corrosion resistance in the marine setting. Sierra manufactures this switch to meet or exceed the performance of the original equipment part it replaces, and Sierra supplies OEM engine manufacturers and boat builders with parts on a daily basis.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
