Master Battery Cutoff Switch with Alternator Protection

We carry the highest quality master battery switches available. This competition-proven switch is rated for 100 amps continuous duty. (See note below on how to spot a lower quality clone.)

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.)

Question: How do I know if I'm looking at the genuine article and not a lower quality clone?

Answer: The terminals of the genuine highest-quality switches are plated with a tin-alloy and are therefore silver colored. Lower quality clones have unplated brass terminals. In addition, genuine switches are shipped with half-height nuts while clones are usually furnished with full height nuts.

Over the years we've heard about dozens of DNF's caused by unreliable master battery switches that were purchased elsewhere. Is saving a few dollars worth risking a DNF?
