Blue Sea Systems Contura2 SPDT On/Off/On Switch
The Contura2 SPDT On/Off/On is a latching three-position rocker switch built for marine electrical panels. It lets you route a single circuit to one of two outputs — or cut power entirely in the center position. Whether you're switching between two bilge pump speeds, toggling between two lighting zones, or controlling a reversible actuator, this switch gives you clean, reliable control in a compact contura-style footprint.

Parts Desk Insights
Best use case: This is the right switch when you need to choose between two circuits — not just on or off. The SPDT On/Off/On configuration is ideal for reversible loads (like trim tabs or actuators) or for toggling between two independent circuits from a single switch position. Unlike a momentary switch, this one stays where you put it, making it well-suited for set-and-forget applications like lighting zones or blower speeds.
If you need a momentary (spring-return) action instead, see the BSS-7935 DPST Off-(On). For a double-pole version with the same three-position action, see the BSS-7937 DPDT (On)-Off-On.
