Shock sensors

[goodpickles]

Can anybody help me find some shock sensors? Electronic goldmine used to have some, but they no longer have them. Jameco has some so called shock sensors, but they are actually mercury tilt switches. Digi key used to have some piezo shock sensors, but they no longer do.

Thanks for any help

How about your local Car Stereo Shop?
They use them on Car Alarms

yes they have them, but they are a complete assembly...to big for my application, and they cost $10-15 each...I have to get the cost to about $2.00
