I want to use transistor or the like as a switch to close and open a ciruit whose voltage is 12 volt DC. Also, the transistor under same 12 v DC source must be operable at max 0.03 amps or 30 mAmps to open or close the said circuit. I want transistor current to be at most 0.03. Any suggestions are most welcome. Thanks.

A MOSFET is better as a switch and it needs no current (mA), only voltage. Search in YouTube for MOSFET switch and you will find what you need.
