This Switch On The Rear Of My Cab ....
<< < (3/3)
Kevin Mullins:
Here's a similar switch that someone may want to look at the markings you typically find on switches like this.

Note how the outer most two tabs have a small line connecting them. (Normally Closed)
Note that the inner most tab has no line going to it. (Normally Open)

Yeah, that's what I thought.

Wired that way keeps the switch in ON when NOT pressed.

If you were to move the two outer most wires to the appropriate inner most tab, then you would have to press the button to turn the machine on. (i.e. put the back door on)

Think of the middle tab as the "Common".
The outer most tab would be "Normally Closed" (always on, off when button pushed)
The inner most tab would be "Normally Open" (always off, on when button is pushed)

right. I'll try swapping those around just to see what happens.I'll probably end up leaving it as is though,because i don't think i have the need to have the need to power the cab off with the back door open since i'm only going to have a PC in there anyway !

(By the way,for any purists out there reading this,I know what some people think of MAME conversions,so I can tell you I'm not butchering a perfectly good working Pacman cab. it had already been converted to another game and all the artwork had been destroyed by whoever it was painting this horrible black gunk all over it. If anything it'll look nicer once i've finished it ! I'm not going to throw away the parts i took out,more likely donate to a worthy collector who can make use of them and keep them going.)
