This competition-proven switch is rated for 100 amps continuous duty.
This switch has three sets of contacts for cars with alternators. The main contacts disconnect the battery while the auxiliary contacts disconnect the ignition coil and short the alternator output to ground through a 3 ohm resistor that is furnished with the switch. A removable actuating key with splash guard, weather-proof cap, resistor and installation instructions are included. (Resistor lead configuration may vary from the photograph shown.)
