FRB,
The vibration switch I am using is the same design as your Adafruit; a movable coil surrounding a rigid post. The numbering is the same in the photos on Adafruit's website.
On the other forum they mention the wobbling coil of these switches makes and breaks contact several times before settling down. This triggers the radar only once however in a 2 second period which is what you want. By the end of 2 seconds the vibration switch has calmed down. I agree, you probably don't need the capacitor to smooth the impulse, or the resistor as it uses the voltage from the radar itself.
I'll give the switch by itself a go.
What have you done with the wiring of three leads to two?
