What have a standing chest freezer in our garage. If it is not locked with a key after use, the door will crack open and the food will spoil. My parents are getting older and twice in two months this has happened. We lost the entire contents both times. I'm looking to put some type of fail safe lock in place. What I'm thinking is something like this https://ift.tt/2LY3Eu4 In the always closed possition, with a momentary switch between the magnet and power supply. I'm looking for opinions on this idea or your recommendation on how to solve my problem in a cost effective way. Thank you. via /r/DIY https://ift.tt/2XYvAA1
