Electrical & Battery Disconnect Switches

Electrical disconnect switches have several important jobs in commercial vehicles and equipment. Battery disconnect switches cut-off electrical power, help protect against electrical fires and theft when equipment is not in use, provide a reliable shutdown of power during maintenance, and protect batteries from excessive drain. Combining high-performance design with industry-leading mechanics and materials, these switches were created for a wide range of applications including off-road, emergency vehicles, material handling, agriculture, marine, and construction. With protection from various environmental factors, you are guaranteed to find a disconnect switch for any application.

Description

Quantity
In shape and design the current isolating switches with mechanical ON-OFF position are very similar to the current isolating switches. There is one difference: while traditional current isolating switches require a minimum current when they are turned on, models with mechanical ON-OFF position absorb current only during the commuting phase or when switches from (OFF) to (ON) and vice versa. Generally referred to as bistable with zero consumption , their switches turn to closed or open state of the electric circuit. They are ideally suited for commercial vehicles and trucks, as well as for marine, agricultural, buses and construction.

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.
