Very popular ignition switch used on my brands of older lawn equipment. 5 spade terminal for magneto ignition, 3 position switch, requires 5/8" mounting hole. Check the terminal locations on the old switch against the terminal layout on the photo. Look for terminal designation on the flat part that the terminals come out of, not the letter stamped on the spade. M = magneto, B = battery, S = starter, G = ground, and L = lights.
