It is wired SPST (single pole, single throw) in a momentary On\/Off configuration with 3 blade terminals, rated 20 amps at 12 volts DC. A red LED lights up the rocker face whenever the switch is pressed into the ON position, making it easy to confirm at a glance that the circuit is active.\u003c\/p\u003e\u003cp\u003eConstruction is stamped brass, injection molded nylon, and polycarbonate, with silver tin oxide contacts for reliable, low-resistance switching over time. The switch is built to resist vibration, shock, thermoshock, moisture, and salt spray, with an operating temperature range of -40 C to 85 C, making it suitable for exposed helm and dash installations aboard boats. It carries an IP66 ingress protection rating for the front panel components and meets UL1500 \/ ISO8846 ignition protection standards for marine products, so it is safe to install near fuel systems and other ignition-protected equipment. The switch body measures 13\/16 inch by 1-7\/16 inches, fitting standard rocker switch panel cutouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 420212-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type:\u003c\/strong\u003e SPST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Action:\u003c\/strong\u003e Momentary On\/Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 3 Blades\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 20 Amps at 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension A (Width):\u003c\/strong\u003e 13\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension B (Length):\u003c\/strong\u003e 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.078 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stamped Brass\/Injection Molded Nylon\/Polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Silver Tin Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIllumination:\u003c\/strong\u003e Red LED indicator, lit when in ON position\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating:\u003c\/strong\u003e IP66 (front panel components only)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -40 C to 85 C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Protection:\u003c\/strong\u003e UL1500 \/ ISO8846 certified for marine use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Pack:\u003c\/strong\u003e 10 each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat type of switch is the Sea-Dog 420212-1?\u003c\/strong\u003e The Sea-Dog 420212-1 is an illuminated Contura-style rocker switch wired SPST (single pole, single throw) in a momentary On\/Off configuration, meaning the circuit is only active while the rocker is pressed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage and voltage is the 420212-1 rated for?\u003c\/strong\u003e This switch is rated 20 amps at 12 volts DC, using 3 blade terminals for the connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the switch light up?\u003c\/strong\u003e Yes, the 420212-1 displays a red light when the rocker is pressed into the ON position, so you can see at a glance that the circuit is active.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the switch body made of?\u003c\/strong\u003e It is constructed of stamped brass, injection molded nylon, and polycarbonate, with silver tin oxide contacts inside for reliable switching.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 420212-1 switch?\u003c\/strong\u003e The switch measures 13\/16 inch by 1-7\/16 inches, sized to fit a standard rocker switch panel cutout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 420212-1 weigh?\u003c\/strong\u003e The Sea-Dog 420212-1 weighs 0.078 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this switch rated for marine use?\u003c\/strong\u003e Yes, the 420212-1 is UL1500 \/ ISO8846 ignition protected for marine products and carries an IP66 rating for its front panel components, and it resists vibration, shock, thermoshock, moisture, and salt spray.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat operating temperature range can the switch handle?\u003c\/strong\u003e The 420212-1 operates from -40 C to 85 C, suitable for exposed helm and dash locations on a boat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 420212-1 different from the 420211-1 switch?\u003c\/strong\u003e The 420212-1 is a momentary SPST On\/Off switch, while the 420211-1 is a standard (non-momentary) SPST On\/Off switch in the same Contura style;
