Sierra Digital Voltmeter — Contura Switch Mount
A clean, low-profile digital voltmeter designed to drop directly into a standard Contura switch cutout — no additional panel modification required. The Sierra EA01080 delivers a precise 3-digit LED voltage readout across a 2.5–30V DC range, making it compatible with both 12V and 24V systems. Self-powered from the circuit being measured, it needs only a 2-wire connection for a fast, straightforward installation. Housed in a uni-body polycarbonate case and IP67 rated, it’s built to handle the moisture, dust, and vibration of the marine environment.

Parts Desk Insights
Best Use Case: This voltmeter is the ideal choice for customers with Contura switch panels who want to add a voltage display without cutting a new hole or using an adapter. It’s a natural fit for helm panels on center consoles, bass boats, and pontoons where Contura-style switch blanks are common — simply replace an unused switch blank with a live voltage readout. The 2-wire self-powered design keeps the install clean and fast. For customers who want the added battery level graph display alongside the digital readout, recommend the EA01090 (11-EA01090) which fits a standard 1-1/8" round cutout instead.
