I used to hate these buttons on cabs BITD. They don't stand up well to mashing and used to get stuck down.
These only stick down because they need to be kept clean . Worst enemy is furniture polish picks up dirt and dries out sticky!
Time in arcades they get fizzy cola / beer etc dust and grime from hands plus cigarette ash on older machines all works to clog the gap between button lens and the socket , also the tubular shaft grimes up against the screw body too
Easy to seperate a good warm soapy water wash and scrub with a toothbrush if necessary cures the sticky age dirt
In addition the spring is available in stronger gauge or can be stretched a bit to increase the pressure tension also you can wash the microswitch allowing it to dry fully for 24 hrs before refitting maybe ?
Don’t stretch spring too much as it may snag on the bulb holder which takes a 12v or 6 volt wedge bulb depending on supply levels available
The star point buttons are simple to illuminate and the lens can be popped off using a craft knife and the legend title or colour can be swapped
The downside is the plastic lens does scratch easy or even crack, but I have hoarded loads over 4 decades just can’t get to most of them on shelves of cash boxfuls of all types of buttons (round square big small rectangle triangle etc) plus with open vein contacts like older invader/pinball flipper style but stored behind a stack of monitors. So out of reach just now sadly.
I just routed these out to show the breakdown of parts so you can clean yours and get them more springy perhaps see pics …..easy to strip down and rebuild it’s just knowing it can be done!
To reinsert the white button shaft into the body you need to fully compress the spring between finger and thumb while the two prongs are pushed into the body.
I may get to them soon if you are really stuck to find any? Hoping this may help folks on here?
