Well made fsr

I used this to make a quiet computer mouse, I removed the left click button, added an Arduino nano with an optocoupler. Worked great. Good product. I was able to solder quickly to the contacts. I could see how soldering too long could melt the sensor.

just works!

Ended up using it in a bending die that I was using to bend a feature in 1/8" steel. When the alignment pin touched down to the floor of the fixture the sensor was used to light up an LED. Was able to make almost a 100 parts before the resistor started to fail. I wasn't expecting much but this was a really cheap but elegant solution for a quick job.
