Iris Contact Sensor v2 - wire for switch?

Here you go.

It is not clear from the picture but you need to connect to the pin that is closer to edge of the board (and make sure that the second pin is not affected).

Disclaimer: I don’t have the board schematic and this is all empirical. I may be shorting the sensor itself, if I am lucky, or it could be a buffer output. In the latter case, if the buffer is not protected, it will die and I stand to lose $11.18. Also, I’ve been using modified sensors only for a month or so, and cannot tell anything about any possible adverse effects on the battery drain. But so far, it’s clicking. :slightly_smiling:
