I appreciate the information. Thank you.I know I said I will drop out but I will add another point
With those push in safety switches, wear in the switch where it clips in plus wear in the switch plus wear in whatever pushes the plunger down can mean the plunger does not move far enough
Particularly with brake switches I put a self tapper into the end of the plunger to make it longer .
Because of their locations it is very hard to back probe them in situ so people push the plunger all the way down to test them when in practice it only goes 1/3 to 1/2 way down
Then some times there is a build up inside the switch so when it is depressed fully the crud is pushed out of the way so the switch now works again .
And remember this is not face book so we know nothing about the mower or you till we are told
So the safe assumption is the person on the other end knows absolutely nothing and dropped out of schooling after kindergarden
This deters us from using jargon that only techs understand which can result in to poster being injured because they did not understand what was posted
There are thousands of people on this forum and unless your thread goes on for a very long time I for one will never remember you as there are up to 100 posts a day most of which I skim over so you could have been here 20 times but few will remember you as we are primarily concerned about your mower problems
Australia does not have a fire arm problem so we tend to be blunt & strait forward ( very similar to Germans )
