Blue Sea 4151 WeatherDeck Toggle Switches [4151]

The Blue Sea Systems 4151 uses an OFF-(ON) momentary action, so the circuit operates while the toggle is held and returns to OFF when released. Nickel-plated brass and phenolic construction resist corrosion in wet marine and vehicle environments. Designed for Blue Sea Systems WeatherDeck panels, the switch can achieve IP67 temporary-immersion protection for 30 minutes when installed with a compatible WeatherDeck toggle switch boot.

• SPST configuration: Controls a single circuit with straightforward single-pole, single-throw switching.
