Would appreciate if someone could let me know the typical function of the gravity plunger relay in Gottlieb early flipperless machines. I am restoring a 1946 GTB Superliner (unable to acquire schematic) and not been able to work out the role of this relay. Thanks Wayne

You have tried Steve Young at The Pinball Resource? I don't have that schematic and am not familiar with that feature I'm afraid...
Otherwise (if you want to try) you wouldn't be the first person to draw
up a schematic of a game without one.

From my notes it provides timing functions. Later this was handled by the control motor. The time it takes to actuate coincides with the time it takes some other coil to fire for example. The slo-drop switches would be tied in with the other coil. Think in terms of the motor switches on later EMs that pulse in order to control some other coils.

Does that use an air shock absorber like some other 30s and 40s games? I find they usually need to be rebuilt with a fresh greased leather washer
to restore the proper action.
