I have this battery powered soldering iron from Canadian tire made by Weller and the power switch is the type where u have to hold, on top of that if u don't hold it in the exact right position it wont stay on. This is really annoying so I did something about it. I am not responsible for any harm you cause to yourself, others or any damage you cause while attempting this instructable.

Step 1: Materials

-Soldering iron
-Knife
-Wire strippers

Step 2: Dissasemble

So start by removing all the screws, there are three check under the sticker that's where two of them are.

Step 3: Switch

Now remove the little black part of the button with a knife simply cut it off and it will pop out then make the hole in the red part big enough to accommodate you're new switch in my case a toggle switch.
