Quoted from paulace:Thanks Ken - why do they bother to do that? Elsewhere in the schematic (see photo), there is a normally open switch that has an "O" beside it. They obviously don't do that with all the switches....is it something they only do on index switches? Why would that be?[quoted image]
Just a WAG here (really asking Ken more than anything else), but I think the "O" is a 'zero', based on the other one you circled that has a '5' next to it. Probably a index number for the contacts?
Then another WAG: no diagonal line is 'normally open' whereas one w/a diagonal line is a 'normally closed'?
