Sea-Dog 420241-1 Large Rocker Switch, SPST On/Off, 15 Amp 12 Volt

The Sea-Dog 420241-1 is a large rocker switch built for onboard electrical panels that need a simple, reliable on/off control. It is an SPST (single pole, single throw) switch with a straightforward On/Off circuit action, wired through 2 blade terminals sized for 1/4 inch connectors. The switch snaps directly into a standard 7/8 inch x 1-7/16 inch panel cutout, so it drops into existing panel layouts without special tools or hardware.

Construction is stamped brass combined with injection molded nylon, giving the switch a durable body that stands up to the vibration, moisture, and handling typical of a boat's helm or accessory panel. The switch is rated for 15 Amps at 12 Volts, is ignition protected, and carries an IP54 water resistance rating, making it suitable for use near bilge pumps, lighting circuits, fans, and other 12 volt accessories on board.
