LED voltage display remote control switch:Low voltage protection: When the voltage is lower than 11.8v, it automatically power off. When the voltage is higher than 13.2v, the remote control be disabled to prevent accidents. [Magnetic lock function] This car disconnect switch adopts a relay, which controls the circuit disconnection through the magnetic principle, and the standby current is 3mA, which is more energy-saving. [Intelligent LED voltage display] The LED voltage display detects the battery voltage at any time. If the voltage is lower than 11.8V, the remote disconnect switch automatically cut off the power after 120 seconds to save electricity. If the voltage is higher than 13.2V, the remote control be disabled to prevent accidental power off while driving, and the power can only be controlled by the button on the switch.
