Has anyone tried one of those very small reed switches and small magnet instead of the usual contact breaker, Hall effect, induction pickups etc ? I was thinking of using a reed switch as it could be made very compact but I am concerned about accuracy of timing and reliability.
The other issue you may have is bounce. Mechanical switches don't close and open cleanly, but rather tend to vibrate or rebound slightly when they first make contact. For some electronic ignitions, this causes the spark plug to fire when the switch makes contact as well as when it opens. Chuck
I would agree with Chuck about switch bounce, but most read switch are short on how much current they are good for. You may find them to fail pretty quick if an electronic circuit is not incorporated into the circuit. So be careful how you use them.Don

So be careful how you use them.DonValid concerns but you can get some high current rating reed switches. And the mercury wetted ones reduce arcing even further: http://www.mouser.com/Electromechanical/Switches/Magnetic-Reed-Switches/_/N-5g2l/Gerrit
