At first I thought they were perfect for my project. To use them to secure and lock a panel in my garden at night to deter theft. I found it convenient to only use one key for both. Unfortunately I went to the opening one morning and the entire toggle switch assembly came out along with the key. I had to hit with a hammer until the screws were unscrewed. The screws themselves are of poor quality and immediately began to rust. I wouldn't recommend it for outdoor use.
