Electrical and Battery Disconnect Switches

Disconnect switches have several important jobs in commecrial 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. Safety is of the utmost importance when it comes to electrical applications, which is why Waytek offers a wide variety of safety related electrical products, connectors, and switches to help keep you and your equipment safe. In instances where the battery is not easily accessible or reaching the battery becomes dangerous, the remote mounting of a battery jumper terminal junction block inside or outside a vehicle allows for convenient and safe jump-starts and charging. For situations where you need to connect two parallel wires or one wire to multiple wires to complete your circuit consider using a butt connector, designed to keep moisture, dust and chemicals out of the electrical connection. No matter what you’re your electrical project requires you’re guaranteed to find all the parts you need at Waytekwire.com.
