Blue Sea Systems 4155 WeatherDeck DPDT Toggle Switch, ON-OFF-ON

The Blue Sea Systems 4155 is a DPDT (double pole, double throw) toggle switch built for ON-OFF-ON switching applications on boats and other marine equipment. It is manufactured for use in WeatherDeck Waterproof Panels, giving it a sealed, corrosion-resistant mounting solution for wet helm stations, flybridges, and other exposed locations. Construction is nickel-plated brass and phenolic, a non-corrosive combination chosen specifically to withstand the marine environment.

This switch is intended for applications that call for a switching action other than simple ON-OFF, or that need a different pole configuration than a standard circuit breaker provides, in installations where circuit protection is already handled elsewhere. Typical uses include generator starters, bilge pumps, horns, wipers, and engine controls. The 4155 is designed for use with the A-Series Toggle Circuit Breaker Mounting Panel, and it is supplied with a mounting adapter so it installs directly into a standard 5/8 inch circuit breaker mounting hole, making it a straightforward upgrade or addition to an existing panel.

Electrically, the switch carries a maximum operating voltage of 250V AC / 30V DC and is rated for 25 amps, with quick connect tab terminals sized at 0.25 inch (6.35 mm) for a secure wire connection. The switch is rated IP67 and meets UL 1500.
