The Mallory Coil Selector is a directional dual inlet, single outlet coil selector engineered for high performance enthusiasts or racing applications operating a dual ignition system. The driver can operate both ignition systems simultaneously or each system independently without moving the coil wire from one coil to the other. Designed to accept as much as 60,000 volts at each inlet, it uses brass contact terminals with spark plug type secondary posts for better wire retention.
