There is a small conduit access fitting below the switch. I checked it with a meter. The switch has power on one side and not the other. I think the push pull cover plate has small alan head screws holding to the box. If I can't find a replacement switch and cover, the box has 3/4" pipe threads.
I was trying not to disturb them, because as you can see the box has been out in the weather for almost 50 yrs. And I don't want to break anything trying to loosen the rusted threads.
I will start by spray a little break free on it this morning in case I need to replace the threaded box along with the switch.
I will run down to Home Depot this afternoon to see if I can find another plunger switch replacement.
Thanks a bunch Steve.
I looked on
Amazon and couldn't find that type of switch.
Im sure there are electrical supply houses in town if need be.
Thank you for the help.
Dan.
