Blue Sea Systems 4180 15A Push Button Switch, Off-On, Backlit, IP67 Waterproof

The Blue Sea Systems 4180 is a 15A, 12V DC off-on push button switch built for marine electrical panels where reliable, waterproof circuit control matters. The button is backlit blue when the circuit is off and red when the circuit is on, giving an at-a-glance status indicator even in low light. The switch ships with five icon labels covering accessory, lights, anchor light, running light, and bilge pump circuits, so it can be dropped into common panel functions right out of the box; a 50-icon label kit is available separately for other applications.

Construction is stainless steel with an IP67 waterproof rating, achieved through an O-ring panel gasket and a molded rear cover that seals out spray and moisture. The switch is reverse polarity protected and terminates in wire leads for a panel-mount installation. It is a normally open, single-circuit switch with 5 available positions and is rated to an upper temperature of 55 degrees Celsius, making it suited to helm stations, cabin panels, and other exposed marine locations.
