Sierra Auxiliary Power Socket — 1-1/8" Panel Mount
A flush-mount auxiliary power socket built for standard 1-1/8" panel cutouts. The Sierra EA01050 accepts standard auxiliary power plugs and features a twist-lock system that securely locks the plug in place — preventing accidental disconnection from vibration or movement underway. Rated at 9–36V and 20A, it’s compatible with both 12V and 24V systems. The illuminated socket is easy to locate at night, and the watertight cap protects the port when not in use. Quick-connect 1/4" terminals make wiring fast and straightforward.

Parts Desk Insights
Best Use Case: This socket is the right choice when a customer needs a panel-flush auxiliary power point with positive plug retention — the twist-lock is a meaningful upgrade over standard push-in sockets on boats where vibration or rough water could cause an accessory plug to work loose. It’s a strong replacement for faulty OEM auxiliary sockets and a clean add-on for helm or console panels where a flush finish is preferred over the surface-mount EA01100. Confirm the customer has an available 1-1/8" cutout or is willing to cut one; for no-cutout installations, recommend the surface-mount EA01100 (11-EA01100) instead.
