4 Problems and Solutions

4.4 Switch Problems

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:

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.
