Single Pole Double Throw Switch gate in Langdale

This gate on Side Pike in Langdale reminded me of a Single Pole Double Throw switch, otherwise known as a landing light switch. It's the way that the gate pivots in the middle but can close to the left or the right. It just looks like the circuit symbol representation. You can find that here https://learn.sparkfun.com/tutorials/switch-basics/all It's decades since I had to teach it but even when I did, I didn't know that single pole means one single circuit connected but double throw means two "on" positions - hence the landing light.
