Micro Switch Amp Rating

That switch looks like it could survive a 6A at 12.5v but work at 3A easily at 12v. At 250VDC it's .3A, 125V it's .6A so if it's a linear slope, .6x10 would be 6A at 12.5v.. 3A should be easily handled. If it won't, put a 10A Bosch behind it, they only take 150ma to trigger.
