Hi,

I just got my schematic for my 1951 Williams Horse Shoes woodrail. Looking at the schematic I am seeing abbreviations that I have not seen before. Below is what I am seeing....

"owe on Flipper Coil" - the schematic shows a closed switch
"cwe on #5 Bumper Re" - the schematic shows an open switch
"cwi on Shuffle" - the schematic shows an open switch

I am thinking that, these are totally a guess...
"owe" means - open when/while energized
"cwe" means - closed when/while energized
"cwi" means - I have no clue??

Does anyone have a "Legend" of some sort that describes the abbreviations I am seeing?

Any thoughts/suggestion?

Thank You
Steve
