It operates in an OFF-(ON) configuration, meaning the circuit is closed only while the button is held or actively engaged and returns to OFF on release, making it well suited to accessory circuits, lighting, anchor lights, running lights, and bilge pump controls. The button face is backlit and changes color to show circuit status at a glance: it glows blue when the switch is off and red when it is on, so operators can read the panel state even in low light without guessing.\u003c\/p\u003e\u003cp\u003eConstruction is IP67 waterproof, using an O-ring panel gasket and a molded rear cover to seal out spray and moisture, and the switch is reverse polarity protected to guard against wiring mistakes during installation. Termination is via a 3 inch bare wire pigtail sized for 8-16 AWG wire, allowing direct connection into a panel wiring harness without additional connectors. The switch mounts through a 7\/8 inch (22.35mm) panel hole and accepts panel thicknesses from.04 inch to.24 inch (1-6mm). It ships with five icon labels (accessory, lights, anchor light, running light, and bilge pump) so the panel can be labeled for its intended circuit; an additional 50-icon label kit is available separately for other applications. The switch is rated for 10,000 switching cycles and an operating temperature range of -20C to 55C (-4F to 131F).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 4181\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Push Button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e OFF-(ON) Momentary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 15 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacklight Color:\u003c\/strong\u003e Blue when off, Red when on\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax.
