The ball, if it was in your photo. Would roll up, touching that long blade. That blade will push on the small plastic spacer, "opening" that contact next to the plastic spacer.
When the Roll Ball triggers that contact. Your game should go to Game Over.
So on this one it is open til ball closes?
My machine the contacts are open, so I checked continuity across the leads and have continuity with them being open.
Thinking there would be NO continuity until they closed...........continuity closed or open Hows that work?
Most Gottlieb have open TILT switches in the tilt relay. Like the bob in your photo.
The anti cheat switches are NC, the bounce switch is NC, back box anti-cheat is also closed. Ball Roll switch is NC.
These closed switches are on the schematic, generally on the lower right side.
Sorry.............72 wildlife. My question is why is there continuity on the leads when the contacts are open?
Power off........... Wouldn't it be the same as if I jumpered across the terminals?
wouldn't think there would be continuity until the contacts closed
Quoted from mrbanjo:Power off........... Wouldn't it be the same as if I jumpered across the terminals?

Open switches can have continuity through another path, but there should be resistance from coils or the transformer. Try reading the ohms. It should be greater than zero when the switches are open, and zero when closed.
