How do Battery Disconnect Switches Work?
Commercial vehicle electrical systems tend to take a lot out of batteries. The main issue is with excessive drain, which happens even if the switch is turned off. Fortunately, battery disconnect switches can help.
Battery disconnect switches completely power a vehicle down, which protects against that excessive battery drain. It also removes all loads and leaks that will eventually destroy your battery. Disconnect switches also aid in helping prevent injury. By disconnecting the power, this prevents technicians from getting electrocuted.
Products to Use with Battery Disconnect Switches
Safety is of the utmost importance when it comes to electrical applications, including battery disconnect switches, which is why Waytek offers a wide variety of products to help keep you and your equipment safe.
