I have had this flexible arm LED work/welding light for a while now, but I have a love/hate relationship with the permanent magnet - stays in place, but a lot of work/effort to reposition. I have seen a youtube video about making your own magnetic power drill that used security lock magnets, so I bought two, which operate at 12v DC, same as the LED light that I am using.
The idea was to make something with two push button switches, one to turn the LED light ON (which I didn't have - it was either always ON or OFF) and a second button just for the magnet. I got the parts a couple of months ago, but until this "long" weekend it was just in my head. Today I finished it. This was the mockup:
I initially wanted to use like a plastic project box, but I felt those were too expensive, and since I had some scrap mild steel I made my own:
Two boxes - one for each switch:
I drilled both sides of the box (top for the switch size - bottom larger, so that I can access wires), and welded two small side plates (one which will have the strain relief). You can see here on the right one of the 12v security locks:
Test wiring/function:
Epoxy and bolt together:
