PB penetrating fluid overnight. Still won’t budge. Will try “hammering”vibration into base to help penetration.

Finally came loose. I moved a screw’s point to various places around the retainer’s perimeter and applied an etching tool to the screwhead for 5 minutes. The micro vibration sank the fluid deeper and shattered the aluminum corrosion enough to let the snap ring plier crack the retainer loose. Yay. Now to see if the switch is salvageable.

Update:Cannot get the switch to budge. I can get a probe around the edge of its slick plastic (PTFE?) and there’s a slight flat spot on the perimeter, but I can’t pry it up from either there or the spring hole. I popped out the green button rubber and tried pressing from that side to no avail.

Jan.24 -Apparently there was a metal strip that exited the switch module and bent underneath the switch to contact the wide end of the spring. Another tongue of chromed metal exited on the opposite side to contact the aluminum base. The spring contact one was totally rusted away. Now I have to get the button module itself apart to see if I can manufacture a replacement for the disintegrated spring contact.

l got the switch apart. Tab going to (negative battery contact) spring corroded away outside switch casing, but intact inside so I can see how it works. Will clean corrosion out of switch and try making a new contact tab.[image|3537484]
