Description This item is a safety quick connect/disconnect connector kits, which allows quick connect and disconnect for winches or other electrical devices. The 4 terminal are made of coated with silver, which features strong electrical conductivity and reduces the resistance to guarantee stable voltage and current. This connector is suitable for quick disconnect/ connect is required such as forklift battery charging and plug in style booster/ jumper cables for vehicle charging. Features - Polycarbonate shell which is a versatile and tough plastic makes this connector sturdy and reliable.- Driver recovery products' quick connector set offers an easy and convenient way to connect and disconnect power to winches, forklifts, chargers, power modules, cars, motorcycles, boats and other electrical devices.- Silver or plated copper contacts inside housings that strongly force the contacts together- Stainless steel springs form a rebuts force between the contacts that holds the connector in the mated position.- Contacts feature a sacrificial tip that allows high current circuit interrupt. Prevents accidental cross mating of circuits.
