Mercury Dual Lanyard Stop Switch

The Mercury Marine 814324A04 Dual Lanyard Stop Switch is a genuine Mercury OEM safety device designed for twin-engine installations. This emergency stop switch system allows both engines to be shut down simultaneously if the operator becomes separated from the helm, helping prevent runaway vessel incidents and improving onboard safety.

The dual-circuit design is specifically engineered for vessels equipped with twin Mercury outboards or dual-engine propulsion systems. When the safety lanyard is pulled from the switch, ignition to both engines is interrupted immediately, bringing the vessel under control and reducing the risk of injury or property damage.

Manufactured to Mercury Marine specifications, the 814324A04 switch assembly features marine-grade construction designed to withstand vibration, moisture, salt exposure and UV degradation. Genuine Mercury safety switches provide reliable operation and OEM compatibility with Mercury ignition systems.

This style of emergency stop switch is commonly found on offshore fishing boats, performance vessels, commercial craft and recreational boats equipped with twin-engine installations. Regular inspection and testing of lanyard stop switches is recommended as part of routine vessel safety procedures.
