Blue Sea Systems 4152 WeatherDeck Toggle Switch, SPDT ON-OFF-ON, 15 Amp 12 Volt DC, IP67 Rated Marine Grade

The Blue Sea Systems 4152 is a WeatherDeck toggle switch built for exposed marine electrical panels where moisture and corrosion are constant threats. It is manufactured by Carling Technologies specifically for use in Blue Sea Systems WeatherDeck panels, and when paired with a WeatherDeck Toggle Switch Boot it carries an IP67 rating, meaning it can withstand temporary immersion for up to 30 minutes. This makes it a dependable choice for helm stations, flybridges, and other on-deck locations where spray and rain are routine.

This switch uses an SPDT ON-OFF-ON configuration, giving the operator three distinct positions from a single toggle. That makes it well suited for combining navigation and anchor lights, running windshield wipers, controlling trim tabs, or any circuit that needs two separate functions plus a neutral off position from one switch. Construction is nickel-plated brass and phenolic, chosen for corrosion resistance in the salt-air and washdown conditions typical of boat electrical systems. Termination is via 0.25 inch quick-connect blade terminals, allowing fast, secure wiring during panel installation or replacement without soldering.

Electrically, the 4152 is rated for 15 Amps at 12 Volts DC and 125 Volts AC, with a 10 Amp rating at 250 Volts AC, and it carries 100 Megaohms of insulation resistance. It is finished in silver and designed as a direct panel-mount switch for Blue Sea Systems WeatherDeck panel systems.
