Posting here, might need to be in the stupid questions (I feel stupid).
I'm trying to use a microswitch to switch a cordless tool under full load. I assumed I would be able to get an off the shelf transistor to do the job, but when I work out the values it would need It gets pretty hard to find anything.
The battery can output 30A, theoretically, and has a full voltage of 20V. Is there PNP transistors that can continually handle 30A? Should I be using a relay or contactor or something else?
I went to all the trouble of jury rigging a setup (picrel) and it worked, so I potted it and it then proceeded to permanently close circuit at first use. I had incorrectly identified the current at 50%.
