Want better control over your boat's bilge pump? This Pactrade marine switch gives you three positions: Off, Automatic, and Manual. In Manual, you hold it to run the pump, and it springs back to Off when you let go—so you can't accidentally leave it on. The Automatic position lets your float switch or sensor take over. It also has a built-in alarm to alert you if there's water where it shouldn't be. The housing is black ABS plastic with an IP65 waterproof rating, so it can handle the damp marine environment. Mounting screws are included. Dimensions are about 2 3/8\ by 4 1/4\, compact enough for most dashboards or control panels. A simple, reliable upgrade for monitoring your bilge and keeping your boat dry. Easy to wire up if you're familiar with basic marine electrical.
