High Performance Hermetic Interlock Switches

The Klixon® 4HVS series of interlock switches utilizes a hermetically sealed snap-acting sine switch to create a high reliability yet cost effective solution.

The 4HVS Series was developed for the most severe environments, and the most demanding applications. Ideal for guarding engine compartments, access and maintenance hatches, electrical cabinets, machinery, and industrial equipment. Its explosion-proof design and one-piece steel case construction make it well suited for fuel wetted areas.
