To fix this, there are several things you can do.
1. add a pull-up resistor
1. add a bypass capacitor
1. shielding on the wire
1. use twisted pair wiring
2. add a bypass capacitor
3. shielding on the wire
4. use twisted pair wiring
A pull-up resistor is a resistor connected between the GPIO pin and 3.3v. The exact value of this is not critical, 4.7k is a common value to use, as is 10k. This ensures that when the switch it open, the GPIO pin will go high.
