[FIXED] Normally open momentary switch and on/off command

Momentary On-Off Switch.pngI have build a Volumio player and have attached an normally open momentary switch to pins 5 (GPIO3) and 7 (GPIO4) and 6 (GND). I can switch Volumio on by pushing the switch. I installed the GPIO buttons plugin and enabled GPIO4 to shutdown Volumio.
A friend told me to use 2 diodes so there’ll be no connection betweeen the two GPIO pins.

This is awesome. Thanks for posting that and the instructions for assigning the button for shutdown. I added it to my system last night with a pair of LED status lamps running off the 3.3v supply and GPIO14 to show power and when the system is booted up and running. It works perfectly.
