4-Button service assembly with plastic mounting bracket for most Stern SPIKE & SPIKE 2 machines, most Jersey Jack Pinball machines & most Chicago Gaming Company machines.
There are some sub-par service button assemblies out there that do not make good contact with the buttons. This makes for a very glitchy experience. These assemblies are not those assemblies. These are the good ones! - "Connecting Type"
