I have been building this mini arcade and part of the project is some push buttons that are mounted to a PCB.
I want to mount these inside the case and then drill hold though and have a button on the out side that pushes though to the button inside to give a clan look. I am sure there must be a name for this kind of "button extender" but I can't find them online if any one can help let me know what I should be searching for.
Thank you.
Why not use ordinary pushbuttons on the arcade and wire them to the board mounted inside it ?
Hi
This is not for the controls, this is the screen controller board, brightness, contrast, etc. So I don't have much flexibility the control board that comes with the screen is what it is.
So will be mounted at the back next to volume control buttons.
I am mounting mini joystick and buttons for game control on the front, they will be just standard mounts.
You will not find them on-line because you need to make them your self to fit your project.
Would it just be like a thin dowl with a retaining ring inside to prevent it comming out?
And a cap on the outside with a small coil spring between the cap and the panel surface!
Thank you. I will have a play around and see what I can come up with.
Thanks for taking the time to answer.
My little digital oscilloscope does the same sort of thing, but all plastic, of course.
But if the board uses ordinary tactile buttons, which it looks like it does, then you could wire your own pushbuttons in parallel with them
Hello DevilWAH
You might 3D print "button extender" by yourself.
I was thinking of 3d printing them a few weeks back. But then the screen on my printer died so waiting for delivery of new elegoo Saturn. But I do intend to 3d print them. 
Bit of an over kill to resolder in micro switches for buttons that will be used only and handful of times. How often do you change the contrast on a screen. It's set and forget.
I honestly haven't seen many TV's / screens that use micro switches for brightness and contrast.
You have a connector with wires to switches?
And you can't change that in any way to fit?
Now way those same wires could have other switches or be spliced?
You can purchase external switch caps or buy those tact switches with tall caps, but most "non-standard" applications have custom made switch caps. You could cut a length of plastic dowel to length and glue to the switch as an extender.
Hi,
My initial idea was to replace the buttons, but that does mean more wires to keep tidy and items to mount.
It's an option, but as the current buttons are perfectly functional, this thread was just looking at the alternative ways of making use of the existing ones.
And then looking at if it's worth doing that or swapping them out.
Cheer.
Well hang on then! Why not splice the existing wires if the existing button wires won't reach? Can you solder or use telecom splices like 3M sells?
Replacing buttons means putting different physical buttons on the same wires or extensions of those wires. It's only mechanical hardware, electrically the same within digital norms as a few ohms should not matter with buttons.
If you don't mind resoldering - extended actuators available:
