FnMag, why don't you just order the switch? That is what I did. Can't remember from where, but just order it. You will never be able to salvage one and get it to work right. I'll see if I can figure out from where I ordered mine and let you know.
Duckie, yes that is a pipe stem. It is from Missouri Meershaum. I cut off the end and then cut the end of an old cheap drip tip off and glued them to together. Works pretty darn good. I can even hold it in my mouth if I wanted to. Although I am always afraid it will drop and make me sad. They sell their stems cheap and you can make them work pretty easy. They have a nice bent style that all you have to do is sand down the end a little and it will friction fit into a carto very nicely. Makes for a fast and easy pipe stem. Just remember they aren't the high dollar style and are a little soft, but they work fine. For the price you can't beat them.
