Lost CNI 3/32 PIN - replacement?

[cosmo]

I lost my 3/32 jack PIN for my 532nm 100mW CNI laser.
I was able to get a 3/32 audio jack from Radio Shak but I have to stick a screw inside to close the circuit to enable my unit.

Does anyone know where to get the replacement PIN for the units?
Id rather not have to get from China.

Thanks....

buy a 3/32 headphones, strip wire at the base, solder the wires together, seal with silicone.
