They apparently figured it took more current to handle the starting task on the M than the H. Thing is they didn't perfect the alignment problem. I have redone a lot of them over the years to make that rod or pedal type push the button straight. It didn't always produce desired results. I changed my own M to H style when I went through the tractor a couple of years ago. When you push that button though you need to give it a good hard push to reduce arcing in switch contacts. Far as the hand pull like a super, well, the new switchs you get are not very well made,(even worse than the hand push mounted type) and when you burn into that stud in starter it is a lot more work to replace stud than just a hand push switch. Have soldered many new ones in over the years.
