Thanks to a network outage which has kicked me off the company network, I have put the 9501 handle on. Even better!
Warning if you swap the handle over: you're supposed to use the mercury switch but mine didn't come with one. I have bodged the ball switch in and it works fine ![Cheesy :D](https://www.eevblog.com/forum/Smileys/default/cheesy.gif)
No, you can choose which type of switch you use, the ball switch is probably the best one as it responds to vibration so it will switch the iron ON quicker, whereas the mercury switch will need to be tipped into a certain orientation before it will switch ON.
Unless you actually order a 9501 handle that states it is specifically for the OLED controller that the handle will not come with either the switches as its a direct replacement for the original Hakko iron which instead relied upon a dedicated iron holder/stand that had a cradle connected to a micro switch fitted to it so that when you picked the iron up, the micro switch would signal the controller to switch on to full power.
So you like the 9501 handle even more than the 907 eh? It does give you more control of the tip.
Postman, (lady actually, quite nice one too) has just been and delivered my new pre-wired 9501 handle which is fitted with the 5 pin plug/socket already for the controller (when it turns up) and that also has the ball switch fitted and also the thermister ![ThumbsUp :-+](https://www.eevblog.com/forum/Smileys/default/icon_smile_thumbsup.gif)

Yeah, the 9501 is smoooove, like buttah.
I wouldn't cut the white wire; I'd solder it to the shell GND along with the black wire on both ends. it NEVER
* hurts to double up on your grounds.

I like the tiny mercury switch; none of my kits came with that. I wonder if it will make the handle feel "sloshy" like the old mercury thermostats I used to bust up for their glass switches? Probably not; the "sloshy" feel was greatly amplified by the bimetal coil... but still.

I do notice the rattly feel of the ball/tickler switch in the handle on my mLiNK S4 station whenever I use it, but that one is a fair bit larger than the one in these and I don't notice it near as much in my T12.
*ALMOST never; I'm certain any of us here could think of SOME way in which it would cause us great pain, given enough time and alcohol to lubricate the cogitative engine. ![Wink ;)](https://www.eevblog.com/forum/Smileys/default/wink.gif)
I think I heard one of the classic traits of a hoarder is stashing stuff everywhere, including other people's houses.
I only moved out of home because it was full ![Smiley :)](https://www.eevblog.com/forum/Smileys/default/smiley.gif)
Heyyyyy... you know, some of us have "help" with that.

“But I don’t want to go among mad people," Alice remarked.
"Oh, you can’t help that," said the Cheshire Cat: "we’re all mad here. I’m mad. You’re mad."
"How do you know I’m mad?" said Alice.
"You must be;" said the Cat, "or you wouldn’t have come here.” ~ Lewis Carroll, Alice in Wonderland
