During reassembly after cleaning I heard the dreaded "snap" and realized I broke the switch... argh. so much for taking it to the range the next day. I looked on gunbroker and found a gouger selling one for $45 plus shipping... ah, no.
On Monday around 9am I called Brownell's(800-635-1321) and simply told the person who answered I needed a switch for my FS2000. In stock and $9 each, I ordered four. They were at my door on Wednesday afternoon.
No hassle, quick shipping, good price. I was impressed and thought I would share. It is getting harder and harder to find that experience anymore.
Now to install without breaking the new ones...
