Marine-Grade indicates that the product is designed for a more demanding application.

Littelfuse marine construction switches are designed to stand up to conditions like ocean water spray that can destroy other types of switches. The rugged switches are also suitable for applications where dust infiltration and water spray can be a problem; like off-road equipment, agricultural vehicles and other dirty, demanding applications.

Special features include rubber caps to protect the plunger, gasket-sealed cases (with rectangular housing switches), moisture repellent insulators, brass construction, or chrome plated brass, or a plasticized solution where the wire leads, body and stem are dipped in a resilient PVC coating to completely seal the switch mechanism.
