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.

Commercial vehicle electrical systems are very demanding of batteries. Excessive drain happens even when the ignition switch is in the off position. Master disconnect switches are designed to power down the vehicle completely, protecting against parasitic battery drain. Cutting off the battery with a master battery disconnect switch removes all parasitic loads and small leakage currents that kill a battery over time.

Disconnect switches also prevent injury of the technicians repairing electrical systems by disconnecting all power. Current drain also happens when the ignition is on, and the vehicle or equipment is idling, like in police cars, ambulances, trucks and delivery fleets. In this case, you can't disconnect the main power, because you still need the electrical system to run. Low voltage disconnect switches are an ideal option. They monitor the battery loads and automatically disconnect only non-critical loads from batteries to prevent excessive discharge.
