FDV 510, Tactile switch and firing switch sizes

[Joey_cope]

Does anyone know what size the FDV 510 is? I also can't find the sizes for the tactile button or the firing switch. It's a 12mm firin switch but I don't know if that is the size for the hole or just the button itself. Last question, there's 4 terminals on my tactile switched but only 2 wires. ...? Lol any insight?

I use a 12.3mm drill bit for my 12mm switches.
I would like to find a good source for those small domed tact switches?

you have 2 poss and 2 neg connections if you take the 4th picture you need to wire one of the top 2 and one of the bottom 2 to make your circuit.

FDV the locking ring makes it 22mm at the top. Without it it's something like 15mm, and the screw portion is 10mm. Lengthwise the entire thing is maybe 14mm. If you go to Fat Daddy's FB page there's a diagram somewhere.
