Pi is Overheating after adding Momentary Switch

ebtalk

I do not overclock my Pi. I decided to add a Momentary Switch on my Pi this morning and all of the sudden it begins to overheat. It was 81 degrees when I last checked and turned it off. Adding a momentary switch wouldn't cause your Pi to overheat would it? If not, what could be the other reasons?

I have heatsinks on my Pi but no fan.

@ebtalk A momentary switch should not cause this behaviour. Its an open circuit between 2 pins that you bridge to invoke an action. They are basically sitting as 2 separate attached wires until you operate it and complete the circuit.

@ebtalk did you solder the wires onto the pins or headers? Maybe there is a short. Did you use pin 5 and 6? Did you write your own shutdown script or use one that someone shared?

ebtalk

Yes. I used Pin 5 and 6 that ETA Prime said to and the exact same shutdown script that was in his video. It did not overheat once in the past two weeks until I installed that shutdown script this morning.

@ebtalk If it did not overheat after you physically attached the button and the behaviour only started after the script was installed then that is your issue. Remove the script. Reboot and see what happens. Then re-initialise the script. If it is the script then remove it and start again. To be honest it should work or not. It just sends a sudo shutdown -h now command to the Pi. Just seems very odd behaviour. Maybe find another script and compare the two.
