It allows for battery disconnection by unscrewing the knob a few turns and reconnection by tightening it. The knob can be removed to deter theft. This switch is rated for 500 Amps surge and 125 Amps continuous at 12 Volts. It includes a 15 Amp fused bypass to maintain settings for computers, radios, and clocks when the battery is disconnected. The package also includes battery terminal markers.
