Sea-Dog 420365-1 Three Position Ignition Switch, Long Shaft, Off-Ignition-Start, with Cap

The Sea-Dog 420365-1 is a three position ignition switch built for off, ignition, and start functions on a boat's 12-volt electrical system. It uses a 13/16 inch diameter shaft in the long shaft configuration, fitting panels up to 1-1/8 inch thick, and connects through three screw terminals for a secure electrical connection. This version comes with a cap for added protection at the panel face.

Ignition circuit rating is 15A at 12VDC and the solenoid circuit is rated 30A at 12VDC, covering both the ignition feed and the starter solenoid trigger in a single switch. The switch body is constructed of polypropylene for corrosion resistance in the marine environment, and it includes two keys so a spare is on hand from the start.

This is a panel-mount switch intended for helm installation where an off-ignition-start function is required with a long shaft and three screw terminals. Sea-Dog also offers a short shaft version (maximum panel thickness 5/8 inch) and versions without the cap under separate part numbers, so confirm panel thickness and terminal style before ordering.
