Nelson Specialties Switch Panels

Nelson Specialties offers Switch Panels with proven reliability for high-performance applications. Switch panels are available in five or seven switch configurations.

Both versions include starter on/off toggle switch and momentary ignition toggle switch. The five-switch configuration includes three additional on/off toggles for accessories, while the seven-switch version provides five accessory on/off toggles. Switches are rated to handle a 200 amp emergency break load, far outperforming commercial grade switches often used with high-performance applications. Screw-down connectors are used, rather than push on connectors, to maintain secure connection during extreme vibration. Internal contacts are designed to avoid chatter, and are silver-plated for superior conductivity. Switches are Aircraft Grade and Military Specification (MS24523-22 for on/off switch, and MS24523-30 for momentary switch) to ensure reliability and consistency. Switch Panels utilize a three-piece bus bar. Switches are available in water resistant or submersible versions. Nelson Specialties also offers many other electrical and ignition components and services for high-performance applications. More information is available at
