Can someone post some pics of Dallas switches? I am having trouble telling the difference between IC's and Dallas switches... Google wasn't much help... Is there an easy way to tell the difference?

∆ this

And Mercury wetted relays

Given how important it is (hazmat)
It's hard to watch out for them having never seen one

For mercury relays,

Attempt to remove or place whole board in hazmat?

For dip (IC) style, only ones in sockets. Otherwise the board is hazmat.

For canister style if you have enough experience to make clean breaks in a PCB you cou punch a hole around it and remove the can from the board. But generally best to hazmat the whole board.

For tube style they usually have a quarter or half turn socket. Push down gently and try to turn it. Some are clockwise some counter-c.

Mercury is a neurotoxin. Impossible to clean up in quantity without experience, and causes toxic stains in organics and cloth. If you aren’t 100 percent sure you can remove it safely don’t try.
