Battery Switches

Our Battery Disconnect switches are designed to cut-off electrical power and help protect against electrical fires and theft when equipment is not in use. They provide a reliable shutdown of power during maintenance and prevent parasitic loads from draining the battery during inactivity. These switches are commonly used in industries such as heavy-duty trucks, RVs, construction, mining, emergency vehicles, marine, bus/transit, military and agriculture. We offer plastic and metal body construction with environment protection ranging from splashproof sealing to IP67, ideal for marine or externally mounted uses. Discover also our selector switch options for switching multiple battery banks. One switch simultaneously switches two battery banks while isolating the battery banks from each other.
