Low Power Consumption: The switch consumes 5mA when in standby and consumes about 3W when the switch is working, which is more energy efficient than new cars. Performance Stable: The external antenna makes the signal farther and stronger. Only for start/stop battery, it can't start your engine. Default design. Convenient and simple: this remote electromagnetic battery switch allows you to move the trigger under the hood to your hand. Operating voltage: stop switch 12V remote, 11-15V operating voltage range, suitable for most cars, small trucks, agricultural vehicles, etc. Long range: car battery disconnect system with distance, kills your car power system with remote control, 48.78m control distance. Specification: Item Type : remote battery disconnect switch Material: ABS, copper, silver Battery model: CR2016 x 1 (integrated) Capacity of battery: 75mAh Operating voltage: DC11-15V Starting current: 200A-360A (less than ten seconds) Standby current: 0.005A Switch size: approx. 45 x 45 x 45mm/1.77 x 1.77 x 1.77in Instructions: Installation method: 1: The red wire is connected to the positive pole of the battery, and the black wire is connected to the negative pole of the battery. This is the power supply for the switch, and the remote control switch consumes very little power. 2: The two large terminals of the relay switch constitute the main switch. An incoming line and an outgoing line, in no particular order, play the role of on-off.3: When controlling the on-off of the negative pole, a large terminal is connected to the negative pole of the battery, and a large terminal is connected to the negative pole of the battery (the positive pole is also the same). Packing List: 2 x Remote Control 1 x Power Switch main supply 1 x copper terminal 2 x battery clamp 1 x copper adapter
