Just noticed the thin shocks for the DW10 are no longer available. Where did you get them?
Looks like the shocks are using their own two-pin connector with 12" flying 2-wire instead of the one included with the DW10?
Those were actually assembled here. They still used the included pin connectors in the DW10. The shock sensors simply come with wire leads.
You are correct, though, those are no longer in the suretyDIY store. The shock sensors are fairly ubiquitous. Here’s an Amazon posting. They are the 5150W.
We found that many DIYers preferred to create them on their own, since they’re easy to make and customize. This video shows how to accomplish the same with an Resolution Product door sensor.
