It is wired SPDT (single-pole, double-throw) with a Momentary On\/Off\/Momentary On circuit across 3 blades, meaning the toggle springs back to the center off position when released from either direction rather than latching on. This makes it well suited for applications like trim tabs, windlass controls, horns, or other functions that should only run while the switch is actively held.\u003c\/p\u003e\u003cp\u003eConstruction is stamped brass, injection molded nylon, and polycarbonate, with a locking ring and lever seal designed to resist water penetration at the panel mount, protecting the switch body from spray and splash in a marine environment. The switch is rated 15 Amps at 12 Volts DC and uses 3\/8 inch and 1\/2 inch terminal dimensions for easy wiring with standard connectors.\u003c\/p\u003e\u003cp\u003eSea-Dog backs the 420109-1 with a 90 day warranty. It is sold as a single switch and is a direct fit anywhere a 420109-1 momentary on\/off\/momentary on toggle switch is specified.\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 420109-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type:\u003c\/strong\u003e SPDT Momentary On\/Off\/Momentary On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlades:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 15 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Dimensions (A x B):\u003c\/strong\u003e 3\/8 inch x 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Quick Connect\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\u003eWeight:\u003c\/strong\u003e 0.058 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 90 days\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514423212\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat circuit type is the Sea-Dog 420109-1 wired for?\u003c\/strong\u003e The 420109-1 is an SPDT switch wired Momentary On\/Off\/Momentary On, so it springs back to the center off position when released from either direction rather than staying latched on.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this toggle switch illuminated?\u003c\/strong\u003e No, the 420109-1 is not an illuminating switch.
