I have no problem turning on and off pins on my rpi4 (using both gpio on the terminal and Gpiozero with python3) however when I connect a wire (which is connected to a switch) to the pin... it turns the pin output to 0. When I disconnect, it goes back to 1.

What is the deal here? When I take the connection and attach it to an always on 5V pin - the switch turns on!

Any thoughts?
