Sea-Dog 420121-1 Lighted Toggle Switch 12V 15A — Product description

The Sea-Dog 420121-1 is a lighted-tip toggle switch built for the helm, dash, or any 12-volt DC circuit on your boat. It's a single-pole on-off switch rated for 15 amps, with a tip that glows when it's on so you can find it in the dark. Brass and polycarbonate construction holds up to life on the water.

Every boat needs a few good switches, and the Sea-Dog 420121-1 is one of those parts you install once and forget about. It's a single-pole single-throw toggle, on and off, rated for 15 amps at 12 volts DC. Wire it to your bilge blower, a set of deck lights, a livewell pump, whatever you've got that needs a clean manual switch.

The lit tip is the nice touch here. Flip it on and the tip glows, so you can see at a glance what's running when you're at the dash after dark. Four blade terminals on the back make wiring straightforward with standard spade connectors.

Construction is brass, nylon, and polycarbonate, so it stands up to the damp and the salt better than a cheap hardware-store toggle. The lever action is firm and positive. You'll know when it's on.

It's a compact switch that drops into a standard panel cutout. Good for a new build, a refit, or swapping out a tired old switch that's stopped making solid contact.
