I have an older model of a makita chop saw that finally needs a new switch... I can not find the exact one in your diagrams. It has the number 651115-2 on the old switch. There are three pairs of screw terminals (six wires). Is there a substitute for this part for an older tool that has worked fine for more than 20 years? I brought it with me to Brazil where I used it building a temple...Thank you
