Sierra Ignition Switch Universal Off‑Run‑Start, White Medium — Sealed 20A Corrosion-Resistant

The Sierra MP41030 Ignition Switch is a corrosion-resistant, universal-fit Off‑Run‑Start switch with a sealed cylinder, non-conductive housing and a 20‑amp rating for off‑road motorcycles.

Engineered for durability in harsh environments, the Sierra MP41030 combines a sealed internal design with a non-conductive outer housing to minimize oxidation, shorts and electrical failure. The medium-sized, white finish ignition switch is built to work across a broad range of off‑road motorcycle applications where exposure to moisture, dust and vibration is routine. Its universal-fit approach simplifies replacement without extensive wiring changes, and the 20 amp capacity covers common lighting and accessory loads.

How does the Sierra MP41030 resist corrosion and oxidation?

The switch incorporates multiple protective features designed to limit moisture and contaminant ingress. An inner seal sits between the cylinder lock and the contact plate while the contact points are treated to reduce oxidation, keeping the electrical path reliable over time.

• Inner seal isolates cylinder from contact plate to block moisture
• Materials and finishes chosen to minimize surface oxidation
• Design reduces exposed metal surfaces that attract corrosion

Will this ignition switch fit my off‑road motorcycle without major wiring changes?

The MP41030 is a universal‑fit switch intended for a wide variety of off‑road motorcycle installations. Its form factor and terminal layout are designed for straightforward swaps, though verifying terminal compatibility and mounting dimensions is recommended before purchase.
