Blue Sea Systems Contura2 DPST Off-(On) Momentary Switch
The Contura2 DPST Off-(On) is a momentary-action marine-grade switch designed for applications where you need a brief, controlled electrical pulse — like triggering a horn, activating a solenoid, or firing an anchor windlass. Press and hold to energize; release to cut power. It's the right tool when you need a switch that doesn't stay on.

Parts Desk Insights
Best use case: This switch is the go-to choice for momentary-duty circuits — situations where you want power only while the switch is actively held. It's commonly used for windlass control, horn circuits, and solenoid activation on powerboats and sailboats. The DPST configuration lets you switch two independent circuits simultaneously with a single press, which is useful when you need to trigger both a signal and a relay at the same time.
If you need a switch that stays on after pressing, see the BSS-7931 (SPDT On/Off/On) or BSS-7937 (DPDT On-Off-On) instead.
