Mercury wetted reed switches feature bounceless operation ...

Use a magnet to switch, or get in the relay form for electical control.

That client's purchasing people couldn't find a supplier of such a switch, the mercury hazmat issue being reported back to me as the problem.

I decided not to get into that issue. Instead, the ball of foil was a whole lot quicker way for me to get the testing done than having to deal with the reported mercury switch availabliity problem.

I suspect the alligator clip alone had the contact resistance of a power MOSFET. in the 10~20mΩ region, possibly much more.

John Dunn

Compared to the load resistances being switched, the alligator clip wasn't a problem.
