About this product
OVERVIEW
The Drag Specialties DS-272108 ignition switch restores reliable engine starting and precise electrical control on period-correct Harley-Davidson Sportster motorcycles.
Designed as a direct replacement for degraded original components, this electrical switch seamlessly mounts behind the handlebars while preserving factory dashboard geometry. It delivers consistent power routing across multiple riding conditions without demanding additional adapters or wiring adjustments.
ENGINEERING & PERFORMANCE
Built to manage both 6-volt and 12-volt electrical architectures, this ignition switch reliably routes current to your motorcycle’s charging and lighting systems during startup and sustained operation.
The internal contact assembly resists oxidation and maintains consistent conductivity over thousands of toggle cycles. Its straightforward on-off-on layout allows rapid system activation, while the 3/4-inch square mounting stem locks securely into standard Sportster steering column bezels for stable physical alignment.

WHY HARLEY RIDERS CHOOSE THIS
Riders depend on this component because vintage Harley ignition circuits frequently develop dead contacts or suffer from stiff toggles after decades of vibration and moisture exposure.
By supporting both 6V and 12V systems internally, the DS-272108 eliminates guesswork during frame-off restorations or dual-harness conversions. The rigid mounting stem and predictable three-stage switch plate provide dependable tactile feedback while removing the need for custom fabrication or extensive harness rewiring.
For Sportster owners maintaining authentic street bikes, this switch delivers steady electrical management that keeps classic machines running reliably mile after mile.
