Headlight dimmer switch mounting screw size?

[Guest]

Any of you guys happen to know the screw size, thread/pitch-wise, of the fastener that holds the dimmer switch locked in the "Off" position on a 1980 GS750?

I removed mine to get some crud off of the switch body and...yep, you guessed it...I lost the little nano-sucker.
The dimmer switch is part #
37421-45012

but I can't find a size for the screw.

Any & all help would be GREATLY appreciated so that I can put the switch cover back on.

The part number for the screw is: 02112-03068. Pretty much all screw measurements in Suzuki's part fiches are going to be represented by the first four digits in the second half of that part number. In this case, it is a M3 x 6mm long screw. I can try to see if I have a spare but I can't guarantee it
