Here is an Electronic switch that I have installed in a PSP Slim. This can be installed in any console and be programmed to turn on and of as many mods as you have. The nice thing about this is that it is set to any button you wish and does not interfear with that buttons original functions. To use the button all you need to do is hold it down for .5 of one second.
