If-Off-Stay-Off Box, power loss safety device

thingiverse

The Stay-On-Off device is a simple yet effective way to prevent electrical equipment from turning back on automatically during a power outage. By doing so, you can avoid damage caused by over-running or low voltage when the power returns. When the Stay-On-Off is unhooked and then reconnected, it will remain off until manually switched on using the button, staying that way until it's unplugged once more. I designed this device for a friend whose fish tank filter pump needed manual priming to function correctly, but would be damaged if allowed to run dry. In case of power outages, an Uninterruptible Power Supply (UPS) is actually the ideal option for protecting devices from damage, however it also costs about $60. Perhaps you might consider alternative uses for this device such as playing a practical joke?
