i originally bought a standard car switch and it tried to start the motor when i hooked it up ,so i went with a marine one and no problems, so you got something there FR!There are two main types of ignition switches. One is for battery-powered ignition systems, and the second is for magneto-powered systems. "MagCD" falls under the magneto powered catagory.
Using the wrong type may just plain not work, or it may cause serious damage to the igniton system.
