My 8N is wired for 12v and uses an on/off key switch in addition to the push button starter. My question is has anyone found a replacement keyed switch that has a "positive" on or off position? What I mean by this is when you turn it on (or off), there's a positive stopping point that "holds" the key in that position until you turn it with an albeit mild force. The one I purchased as a replacement does not have this and any type of pressure or touching of the key will move on its own thanks to the weight of other keys or a very mile bump. Any part references for a replacement would be appreciated.
