This is a handy tool for working on heavy/dangerous equipment that needs to be serviced powered on even though removing the access panels (for safety reasons) powers them off. It helps to bypass your "Line Interrupt Panel Mount Pushbutton Switch" (F80 series with button barriers) which is usually incorporated as a means of detecting when humans have entered the system and it's time to shut things down so that fingers/limbs/heads aren't lost during servicing of said equipment.

If you're in a pinch and don't have time to order and wait for Cherry part numbers 0014-4945 or 0014-5451 (aka 'dogbones'), then feel free to print this one out and cherish it always. Y'know... cuz it's cool.

Use with caution of course...
