Seen on a french forum an idea to use a mercury tilt switch as a contact to emulate the Tegra home button.
" hackintendo com ! tutoriaux ! switch ! modifier-son-joycon-rcm-avec-contacteur-mercure" (replace ! with slash and add the missing dots ...)

Besides the fact the guy uses pins 10 and 9 (I would prefer 1 and 10) what do you think of this idea ?
When the switch is used vertically with the joycons attached no contact is present, when upside down the contact is done.
But when the joycon is detached, there could be a contact during motion or when the joycon is horizontal... Is this a problem ?

Mercury is highly toxic and import is forbidden in some countries. I would not recommend this. There are similar switches without mercury available.

Besides the toxicity what do you think of using a tilt switch inside the joycon ?

You could insert a tilt switch, but I'd prefer using a reed switch. Hold a magnet on it, check. Take the magnet away, normal joycon.

I would just solder a 8-10k resistor in there and be done with it but if you are happy with it go for it. But keep in mind you will need a resistor anyway because i bet you don't want the Joy-Con disconnecting randomly (based on angle) which is what would happen each time the switch is active and shorts to GND.

Do you mean that connecting pin 10 to ground disconnects the Joy-Con ?
And adding a resistor in serial would prevent this ? Good to know, thanks.

Yes, a resistor would limit current flow to just enough for RCM detection but not enough to break the communication between Switch and Joy-Con. The other pin is actually used while the Switch talks to the Joy-Con.

I used a magnetic reed switch. Then just buy a really powerful magnet and store it in your bag with your Switch. Whenever you want to RCM, just hold the magnet to the bottom portion of the joycon and hold volume up! Works perfectly every time and it was a pretty simple solder job. I'm still not allowed to post links so I can't share the link but just search for "magnetic reed switch". The tutorial I followed was by gallymimu!

EDIT: That was actually my fifth post so I can post links now. Here's the tutorial I followed: https://gbatemp.net/threads/tutorial-another-magnetic-reed-switch-rcm-installation.505438/
