MSD
RPM Activated Switch
This MSD RPM switch can perform a variety of functions, from turning on a shift-light or solenoid to engaging an MSD Timing Computer at a certain RPM.
Works with 4, 6, and 8 cylinder engines and will switch up to 1.5 amps. Includes a normally open and normally closed connection so that it will turn things OFF as well as ON at the desired RPM. Utilizes standard MSD RPM Modules (not included).
