4.4 Switch Problems

Original ball and chain tilt assembly
Williams A-15361 Tilt Assembly




The original "ball and chain" tilt assembly is very flimsy and not very good. It is suggested to replace it with a Williams # A-15361 Tilt Assembly for much better operation since it uses standardized parts.

You can also use these Marco Specialties parts along with two 6-32 wing nuts to make a complete tilt assembly:

(1) # 04-10346 and (1) # 20-6502-A


Playfield standup switch on Las Vegas



The standup switches look like bent up paper clips just like the switches on Sentinel/Wonder Wizard home pinball machines. These switches must be kept clean and shiny to work properly. The circled area is the switch.
