Auto Master Switch with Remote 240A Kill Switch 12V Remote Disconnect Switch with LED Voltage Display(with 1 Key)

Auto Master Switch with Remote, 240A Kill Switch 12V Remote Disconnect Switch with LED Voltage Display Automatic Operating voltage range: 6–30 VDC Compatible with 12 V and 24 V vehicle systems Automatic detection of defective voltage threshold and automatic disconnection RF frequency: 433.92 MHz, supports self-locking mode LED indicator for ON/OFF status Standby current consumption: 700 µA Driving process and ignition error trigger protection Operating temperature range: –20 °C to +100 °C Rated switching current: 250 A Instantaneous switching current: 500 A Voltage loss protection thresholds: 11.8 V ± 0.2 V (for 12 V systems) or 23 V ± 0.2 V (for 24 V systems) Power loss delay: 60 seconds , automatic disconnect after 120 seconds Standby current: 700 µA System automatically identifies 12 V vehicle systems when supply voltage is 6–18 V, and 24 V vehicle systems when supply voltage is 18–30 V. When supply voltage exceeds 13.3 V (12 V system) or 26.2 V (24 V system), RF remote control is disabled to prevent accidental activation during. When supply voltage is unstable, the system enters trip-triggered protection state. When supply voltage is low, the system enters ignition misfire protection state. Remote control pairing instructions: Interlock mode — Press and hold the manual ON button for 3 seconds until the LED flashes three times to enter learning mode; press the ON button on the remote control; upon successful pairing, the LED flashes three times.To pair additional buttons, press another button on the same or different remote; successful pairing confirmed by three LED flashes. Learning mode exits automatically if no is received within 30 seconds. Clear all paired codes — Press and hold the manual ON button until the LED flashes eight times.During this process, flashing three times indicates interlock mode learning, four times indicates self-lock mode learning, five times indicates click-move mode learning, and eight times confirms code clearance. Up to 20 codes can be stored, supporting up to 10 remote controls simultaneously. This is not an OEM product.Brand/model references are included solely to assist with compatibility identification.
