A shame the manufacturer can't (cheaply) make custom button colours.

I occasionally visit Reno and it's interesting to see the latest ways to entice people to sit in a chair and feed a slot machine. The pushbuttons now have full color graphic displays built in. A typical slot machine has a number of animated graphic buttons, plus all the graphics on the main screen. It's quite the visual overload. One day, your pinpoint button will have a graphics display in it. Not sure why yet.

Boy replacing the switch is hard.
Its behind the main board which is held in place by the potentiometer ,its nut is behind the faceplate but i really didnt want to remove that incase i bent it in the effort.
I then tried unsoldering the pot from the board this was almost impossible using a desolder pump (both heated and using the iron) as the solder was i expect lead-free? All i managed to do was unsolder R47 by mistake (luckily i noticed and recovered it ) trying to solder it back on was hard its tiny even under a USB microscope you have to pin it in place with a pin the solder it both ends trying it without holding it in place just means it sticks to the iron !
In the end the best way was to destroy the switch then remove the huge amount of hot glue by pushing it to the inside from the front and cutting it up with a red hot scalpel and cleaning the shallow dish it sits in soldering to wires unsoldered from the old one and hot glue it back in place.
I cut the 4 wires from the battery box to give more leaway getting to the back of the switch and soldered them back together with some heat shrink to protect the joints.This lets you remove the whole head unit from the stem making it easier to work on
T
Touch wood its working ,the switch works great at the lightest touch unlike before ,not a job i would recomend but worth the effort if your daring ,total cost about $5 in english money lol

Come on then Chester, tell us where you got the switch from. I couldn't find any U.K supplier after a quick search, only buying from Digikey's UK site, which would cost a fortune.

Ignore the colour shown it is red

[Skippy]

Thanks for that, a shame they don't have other colours.
The best I could come up with was RS components, who only mysteriously sell the green one, with MOQ of 5 pieces.

Farnell list them, except they are from the US, so there's a stupid carriage charge etc.

You can have it any colour you want buy those coloured round sticker things kids use in the same size and stick one on loll

Yes, I have some black vinyl stickers, that was one of my options. And also some thin brushed-aluminium sheet that's self-adhesive, that may look nice, all I have to do is find it ....
