The quake and tsunami caused a major power outage that cut communications around Palu making it difficult for authorities to coordinate rescue efforts.

When you're tired of opening and closing those blinds day after day, when you're on vacation and there's no one there on the weekends to be turning off and on the controls, or when there's a power outage, and you have no electricity to rely on, these thermo bimetals will still be working tirelessly, efficiently and endlessly. Thank you.
