Not for use with the Pro-Mag 44.


The switch is rated at 15 amps so it can handle the power of the Pro-Mag 12. The housing is designed to survive high impacts and features a molded-in elastomer seal between the toggle lever and bushing. The beefy aluminum housing provides a secure mount to withstand extreme racing conditions. (Supplied with the PN 8106 Electronics Points Box.)
