The High Current Dual Battery Isolator Relay 4 Pin 12V AMP 500A Car Starter 24V Auto Power Switch Start Contactor relay is a key component in managing the power supply in a vehicle with two batteries. This relay isolates the two batteries, preventing them from discharging each other when the engine is turned off. It features a 4-pin design, a high current rating of 500A, and a 12V AMP rating, suitable for most cars and light trucks. Its latching relay design means it only needs a momentary signal to switch on and stay on until a second signal is received to switch it off, making it an efficient and reliable power switch.
