Blue Sea Systems 4154 SPDT Toggle Switch, (On)-Off-(On), for WeatherDeck Waterproof Panels

The Blue Sea Systems 4154 is an SPDT (On)-Off-(On) toggle switch built for panel-mounted circuit control aboard boats and other marine or outdoor equipment. The momentary (On) positions on both sides spring back to center-off when released, making it suited to controls such as generator starters, bilge pumps, horns, wipers, and other engine or accessory functions that call for switching action other than a simple ON-OFF, or where circuit protection is handled by a separate device rather than the switch itself.

Construction is nickel-plated brass and phenolic, chosen for non-corrosive performance in the marine environment. The switch terminates in 0.25 inch (6.35 mm) quick connect tab terminals and ships with a mounting adapter sized for a standard 5/8 inch circuit breaker mounting hole, allowing it to install into an A-Series Toggle Circuit Breaker Mounting Panel. It is manufactured for use in Blue Sea Systems WeatherDeck Waterproof Panels, and when installed together with a WeatherDeck Toggle Switch Boot it carries an IP67 rating for temporary immersion of up to 30 minutes.

The 4154 is part of the 4150-4155 WeatherDeck switch group and is made in the United States.

Frequently Asked Questions

What does the (On)-Off-(On) designation mean on the Blue Sea Systems 4154 switch? It means the 4154 is a momentary switch in both directions: pushing the toggle to either position closes that circuit only while held, and it springs back to the center off position when released.

Is the Blue Sea Systems 4154 toggle switch waterproof? It carries an IP67 rating for temporary immersion of up to 30 minutes, but only when the 4154 is installed with a WeatherDeck Toggle Switch Boot in a WeatherDeck Waterproof Panel.

What size terminals are on the 4154? The 4154 uses 0.25 inch (6.35 mm) quick connect tab terminals.

What panels is the 4154 designed to fit? This toggle switch is manufactured for use in Blue Sea Systems WeatherDeck Waterproof Panels and is also compatible with the A-Series Toggle Circuit Breaker Mounting Panel.

Does the 4154 include its own circuit protection? No. The 4154 is a switching-action device intended for use where circuit protection is provided elsewhere in the system, such as generator starters, bilge pumps, horns, and wiper circuits.

What is the 4154 switch made of? Nickel-plated brass and phenolic, a non-corrosive construction chosen for marine and outdoor durability.

How much does the Blue Sea Systems 4154 weigh? 0.1 pounds.

What is the 4154 typically used for? Common applications include generator starters, bilge pumps, horns, wipers, and other engine controls that need switching action beyond simple ON-OFF.

Does the 4154 come with mounting hardware? Yes, it is supplied with a mounting adapter sized for a standard 5/8 inch circuit breaker mounting hole.

How is the 4154 different from a push-button version in the same WeatherDeck switch series? The 4154 uses a toggle actuator, while other switches in the 4150-4155 WeatherDeck group use a push-button actuator; both provide switching action separate from circuit protection, but the toggle style lets you see and set the lever position at a glance.

Where is the Blue Sea Systems 4154 manufactured? It is made in the United States.

What voltage is the 4154 rated for? The 4154 is rated for 24 Volts DC operation with a 25 Amp current rating.
