Disassemble 7800 Joystick?

[toymailman]

Does anyone know how to take off the joystick handle from the 7800 controllers? I have some that don't work well and I would like to clean and replace the contacts but it is too difficult to get to them with the joystick handle in the way.

 

I did a search on this but nothing popped up.

I'm interested in this too!

 

Can any type of tape (Scotch) be used to cover the contacts (what is the official name for those little metal re-boundy things)?

 

Thanks!

IIRC you have to just pull off the knob (fnar fnar)

Was there supposed to be a Rik Mayall/Ade Edmonson double entendre knob joke in there somewhere?

 

I need to know this too because recently I somehow managed to break off the post that the bottom screw goes into when I squeezed the controller a little too hard so I need a new top plastic to replace the broken one.

The switches are called "dome" switches. I've seen three types used: 3-legged, 4-legged, and complete circles.

 

For the CX-40's, I position the cleaned switches (on a cleaned board) with simple scotch tape. Then I seal 'em all in with clear packing tape. Works like new after this!

 

I would like to be able to perform this on my 7800 controllers too. I tried pulling the handle off, but it feels like I will break it due to the force that is apparently necessary. Is this really how they come apart?

Well I thought it just pulled off, but maybe I am wrong, so try this AT YOUR OWN RISK!

There are two screws in the bottom of the stick you remove to gain access to the inside. You shouldn't need to remove the handle from the top portion of the stick to work on the contacts.

Pulling it off worked!

 

I was able to fully disassemble it and give it a thourough refurbishing and cleaning.

 

Works and looks like new now.

Thanks for the pics. Do you have any of the tape you used to hold the domes back on? A clear packaging tape? If the domes are rebounding, do you just apply a little pressure on them to bend them back into bouncing status?

I first use a small amount of scotch tape just to hold each of the dome switches in place. Then I cover the whole switch area with clear packing tape. Finally I poke/cut the holes out as needed to reassemble it.

 

I don't apply any pressure on the dome switches. I just tape them back on.
