Need Help finding a mechinal shock sensor

Digi Key used to have them, but the no longer do...At Mouser I have to take 2000, anbody know of other supliers that may have it?

I bought some from Jameco pn 235926cx. ($1.49 ea)
They worked fine for me, but some were a little more sensitive than others
They are a two lead normally closed,open on impact. Don't know if they are what you're looking for..

The Electronic Goldmine is selling airbag G force sensors for $1.00 PN: G14784 It is a normally open, momentary switch.
