Xpert B3210 Electronic Switch
At the time of writing this, AMain does not have the dimensions of the switch listed, nor do they have any mention of the battery behavior, but I believe this hasn't been out long so it's understandable.

The switch is 29.1 x 18.1 x 12.5 mm, and actually that 29.1 mm doesn't include the wiring coming out. Including the wiring (folded flat against the switch), the effective length is about 35.2 mm. Be careful trying to squish it into place as the wiring insulation will tear off easily right where the wires meet the plastic.

I purchased this for my Losi 8ight RTR, which is equipped with the "gen III radio tray", and it does not fit. The screws line up, but the box of the switch is too big. Tried making more space in the tray with a Dremel and a routing bit, but for it to fit there will be a large clearance hole. I wouldn't mind this too terribly bad, but then I read in the included instructions that the switch draws a small amount of power from the battery when turned off, and can ruin lipo packs if left plugged in for long enough to zero out the battery. How long that would take, I don't know, but I've been known to have unplanned multi-month gaps between playing with RC cars so this wouldn't be good for my equipment. Perhaps it's common knowledge that all button-style receiver switches draw power even when turned off, and I had heard about some button-style switches being like that, however I was hoping this one wasn't that way given that there was no mention of the battery draw in the description. Unfortunately I won't be using this switch and will instead keep using the stock mechanical switch. Hope this helps.
