Rpm Activated Switch Kit

The MSD RPM Activated Switch Kit (Model 8950) is a chip-adjustable, single-circuit RPM switch designed for performance ignition systems that require precise engine speed-based control. This component is essential for tuned engines, drag racing applications, and high-performance street vehicles where RPM-dependent switching enhances reliability and efficiency.

The kit features adjustable chip-based calibration, allowing technicians to set the activation point within the switch's operational range without complex reprogramming. This design focuses dedicated switching capacity on one critical function, reducing electrical load distribution and minimizing potential interference with primary ignition events.

Performance tuners and engine builders rely on MSD's RPM-sensing products to prevent component damage from premature actuation and to optimize power delivery. Buyers typically specify this switch when building race engines or upgrading carburetor-based hot rods with electronic fuel pump control.
