How to wire coin up buttons to be toggled on/off
(1/6) > >>
QuixoteQuest:
My arcade manufacturer built our arcade with a working coin door. But we also have "free play" coin up buttons on the CP, too. I'd like to use my coin door as a portioning device for my sons. Therefore, I'd like to make the CP coin buttons able to be toggled on/off. And I'd like to do it more elegantly than merely plugging/unplugging the quick disconnects from the microswitch by opening up the CP. (I think my 10 year old could easily figure out how to reattach them.)

So my thought is this: Could I cut the non ground wire going to each coin-up button, then wire on an extension to each of the two pieces. Then I could wire each set of two wire extensions down inside the cab behind the locked coin door and hook each end to some sort of always on/off switch where one side of the wire goes on one terminal. The other wire goes on the other terminal. Then when the switch is turned "on" the circuit would be completed and the free coin buttons would work (in addition to the coin door). When turned off the circuit would be broken and only the coin door would work. I'm sure there is probably some kind of switch that could be mounted right to the surface of the wall on the inside behind the coin door that wouldn't require drilling all the way through the wall to mount.

Pardon if very elementary question but I just did my first DIY project yesterday of wiring an extension to my PC power button out to the underside of the CP, so now I'm full of ideas of how to tweak my cab more. This seems like an easy mod, but I want to be sure it is the N-O connection I should break on the coin-up switches and not the COM/ground. And could I take both coin buttons and wire them into the same switch, so both would be open or closed with the same switch?

That would do it, unless he's smart enought to take the wire from the coin door to the CP buttons.  :banghead:

But this are lock so, can't get it.
Now, if he realize that SAVE STATE works, and when the CP buttons work for credits, he just put TONS OF CREDITS so when he start the game over, the credits are still there  :banghead:  :o

Is that box using some sort of encoder?  what is it that you have?  i was thinking of using a shazam key and hiding all my free coin keys under the p1 keys and then hiding the shazam button somewhere

Yep, Save State could definitely be the workaround  :)  Well I won't tell him if you won't :)

I don't need the cab to be impervious. It's not a commercial unit or anything. But a simple, and more elegant solution to switch on/off free play than plugging/unplugging the CP coin-up buttons would be a fun little DIY project.

What I did was wire the ground to the switch and then to the credit button.  Wire the coin door to a common block and wire the credit button to the same block.  Flipping the switch will disable the button.  You can see the switch in the pic (middle right) and the common block.
