2.4ms - toggle - old McGILL (hot glued terminals) #13

Open adamfk opened 6 months ago

adamfk commented 6 months ago

Same as https://github.com/adamfk/bouncy-button-data/issues/12, I just hot glued the switch terminals so that they couldn't shift or vibrate.

TLDR - way better with glue!

The switch performed WAAAAY better when the switch terminals were secured with hot glue. Max bounce was 2.4 ms (vs 52ms), and also the number of transitions went way down (max 305 vs max 977). Resistance also went down 2.6 ohms (vs 10-20 ohms).

Before gluing, I noticed that I could wildly change the switch's resistance by shifting the switch terminal. It could range from disconnected, 1 Meg, 2k, 20, or 0.9 ohms. To get the best reading, I had to slightly tug the left switch terminal to the left (outside).

Once I was fully done gluing, it settled at 2.6 ohms.

🕵️ Your Observations (optional)

As noted above, the switch did WAY better when hot glued.
