Blue Sea 7933 Contura II Switch SPDT Black - (ON)-OFF-(ON)

The Blue Sea 7933 Contura II Switch SPDT Black in (ON)-OFF-(ON) configuration is a marine-grade electrical switch designed for applications requiring independent control of two circuits with a shared off position. This switch is ideal for managing dual battery banks, controlling separate navigation and cabin lighting systems, or operating independent pump circuits on larger vessels.

Engineered to withstand the rigors of the marine environment, this SPDT (Single Pole, Double Throw) switch features a two-position design with center-off, allowing users to select between two independent on positions or fully disconnect both circuits. The construction provides resistance to corrosion and UV degradation, ensuring longevity even when exposed to sunlight and saltwater spray.

Cruising anglers, liveaboard sailors, and commercial fishing operators will find this switch particularly beneficial for its reliability and ease of integration into tight panel spaces typical of galley, helm, and engine compartment installations. The Contura II series is known for its smooth, positive detent action that confirms contact engagement, eliminating uncertainty during operation.
